erp5_simulation: Display Divergence dialog even if there is nothing to solve (same as legacy Simulation Dialog).

This fixes the following Site Error when there is no Divergence to solve:
  AttributeError: 'NoneType' object has no attribute 'SolverProcess_getSolverDecisionList'

This may happen if user selects 'Solve Divergence' Action and solve
Divergences, then immediately goes back and selects again this action
whereas there is actually no Divergence to solve.

Selection.__call__() calls getParams() and as getParams() can be called
directly from many places (such as SelectionTool.getSelectionParamsFor()),
it makes more sense to have it here.

This reverts commit 5fac6732:

  When the Divergence is solved and user goes back to the main view, the
  button is visible but when user clicks ont it and if Activities have
  been processed in the meantime, this will raise an AttributeError
  because newSolverProcess returns None and there is nothing to display.

  This happens even when adding Delivery_isDivergent() as a guard
  because it still returns True if Activities are running in background.

count_method was removed from Base_viewFieldLibrary/my_view_mode_module_listbox
used by Resource Module ListBox (76282344) for performance issues when
countFolder is called with a Module containing > ~50k documents but this
should not be relevant for Resource Modules.

simulation: MultiPropertyEquivalenceTester was missing from Variation Divergence Tester Portal Type.

With Legacy Simulation, when Adopting Prevision, the Builder was called
again and the value was set either at Delivery, Line or Cell level
according to the Movement Group definition. Implement the same kind of
behavior for New Simulation.

With ZODB Components, getBusinessTemplateList() only returns the test
bt5 (as given on the command line, such as BT_TITLE:testFoo) and later
it resolves dependencies.

So filtering bt5 to be updated should be done as late as possible...

This makes more sense as all Tester inherits from EquivalenceTesterMixin,
even project-specific EquivalenceTester classes.

Default values for tested_property and tested_property_title must not
be of type tuple any more since theses properties are no longer multi
valued

With latest simulation, the explanation given to user when solving a
divergence was not good enough :
- Property ids were displayed without possibility to display
  business word (like displaying 'stop_date' instead of
  'Delivery Date'
- Some message was displayed in the solve divergence dialog whatever
  was the equivalence tester behind. Therefore, customizations of
  messages made a equivalence tester level were not displayed to user

Therefore, following was done:
- in solve divergence dialog, include the message generated by the
  equivalence tester
- use tested_property_title to allow using business words to describe
  properties having divergence
- most equivalence testers are written in a way to evaluate divergence
  on a single property. To have better UI configuration of such equivalence
  testers, change tested_property and tested_property_title properties
  type from "lines" to "string". This required to add some backward
  compatible code.
- use Variation Divergence Tester to show a case of an equivalence
  tester using different properties. For this, add a property sheet
  dedicated to multi properties equivalence testers
- update propertysheets to allow translating tested_property_title

Improve default dialog by avoiding doing "update" action to see solver parameters. Instead,
use javascript to automatically fill the "parameter" column when a solver is selected. Since there
is not yet good solution to have this in both legacy user interface and new interface, use a
separated business template instead of just changing the original dialog.

Use a lot proxification to avoid duplicatation of configuration.

Followup of 4b664ba: When comparing Trade Model Rule input_movement from
AmountGenerator and decision which is a Simulation Movement.

This fixes test_13_AddAllowanceForOutsourcingOrder.

getTradePhaseMovementList() returns temporary SM with appropriate arrow
and dates but these temporary SM have their corresponding Trade Model
Path as a parent which means that Simulation Movement API is partially
unuseable (such as getting parent Applied Rule...).

Moreover, it seems strange for a Simulation Movement to not be a child
of an Applied Rule.

Therefore, create the temporary SM as a child of its corresponding AR.

When RSPL/RPPL Invoice Lines are on the same SIT TML as its
corresponding SO/PO IL movements, the sum may be 0 and there is nothing
wrong about it. This was implemented in Legacy Simulation.

FloatEquivalenceTester does nothing if quantity_range_{min,max} are not defined so raises an exception showing the misconfiguration.

This should have been added and handles twisted use cases such as:
  1. Install bt5 with ZODB Component C1 using version_priority V1.
  2. Install another bt5 adding version_priority V1.
  3. Install Portal Type using C1 as type_class.
  => No reset was done after 2., so C1 was not added to ZODB Component
     registry_dict (__registry_dict) and thus ignored.

This only happens when using ZEO (see source code comments).

Steps to reproduce:
  1. Edit a ZODB Component in one tab.
  2. At the same time, run Unit Tests in another tab.

As there may be several trade_phase which could be set on a Trade Model
Path, all of them should be displayed in ListBox and not only the first
one.

This reverts commit d6b94272.

Listbox navigation was broken because of this change.
