These activities may already be running, and deleting them would cause
validation node to violate activity dependencies. For example,
already-running indexation activities will not be waited upon, causing the
unindexation activity spawned below to potentially finish before ongoing
indexation, leading to a catalog persistently inconsistent with object
database.
If these activities are not already running, then CMFActivity will anyway
discard them upon discovering that their execution context does not exist.
And if these activities are failed, then it is a site maintenance issue
(one should not keep failed activities for too long) and must not be a
common case, and not really worthy of handling here.
Also, rework a CMFActivity test checking that activties already-spawned on
a later-deleted context get discarded instead of being executed. Previous
test implementation order was to work around the activity deletion
removed in this commit. The implementation used here is more natural.

As a consequence, reduces portal type duplication: Solver Tool portal type
is also present in erp5_simulation, and does not work without it installed.

Also, install erp5_simulation before erp5_trade in tests.
Note for testFunctionalKM: not moving erp5_simulation_test as this BT also
depends on erp5_trade and not just erp5_simulation.

trade_phase/production is already present in erp5_mrp. Add a dependency to
it, and remove it from this Business Template.
trade_phase/production/delivery: Likewise.
Also, remove the test-dependency to erp5_mrp as it's now a regular
dependency.

This BT contains the same category twice.

Bank Account, Currency{, Module}, Currency Exchange {Cell,Line} already
exist in erp5_base, which is a dependency of this Business Template at
least through erp5_trade.
"composition" and "variation" Base Categories exist in erp5_pdm, which
is a dependency of this Business Template via erp5_trade.
"site" Base Category exists in erp5_base, which is a dependency of this
Business Template via erp5_trade.

classification is already provided by erp5_dms, which is a dependency
of this BT already.

requirement is also present in erp5_project. So add a dependency on that BT
and remove the duplication.

This BT achieved the rare feat of containing the same document twice.

region/europe/western_europe is also present in erp5_tiosafe_test, which is
already installed in the same unit test. So add a dependency on that BT and
remove the duplication.

currency_module/euro is also present in erp5_tiosafe_test, which is already
installed in the same unit test. So add a dependency on that BT and remove
the duplication.

otherwise naturalWidth/naturalHeight may be 0

Avoids accumulating useless connections when a single test file contains
multiple files.

Sorting on all documents is a performance killer.

In case no query parameter is available, do not trigger any allDocs
calculation and do not display the listbox, as results would be
meaningless.

For instance, typing a backslash in a relation field does not crash the ui anymore.

This property is only conditionally set, which causes distracting error
when something goes wrong. If we really want to check that the expected
code path was followed there has to be a better check and a more debugging-
friendly error than an AttributeError.

While such activity parameter combination does not make sense, it is
technically possible to spawn activities with a group_id set but without a
grouping_method_id.
The consequence is zombie activities: they never fail, do not prevent other
activities from being executed, but and are permanently run on the node
which reserved more than one because:
- all but one activity is in MESSAGE_NOT_EXECUTED state, forcing an abort
- finalizeMessageExecution does not understand that MESSAGE_NOT_EXECUTED
  activities may not have failed, and itself fail while trying to detect
  the failure type (ConflictError vs. others), failing to free & postpone
  the activity, in turn failing to bring it to eventually permanent failure
  state.
Make those conditions consistent, and use tuple-unpacking to detect any
future inconsistency much earlier, simplifying debugging.

group_method_id column is declared "NOT NULL", so it can only be None if
getProcessableMessageList could not find any activity, in which case this
code is not executed ("if message_list" is false).
This simplifies two "if" statements.

So called "click-click" element.

What happens is that in same script (line 907) we want to calculateHateos for
restricted case without passing (I consider explict decision) the response.
What happens is that script will try to redirect to login form using non existing
response parameter. So fix is redirect ONLY if we do pass response.
This allows a Web Site to work with Anonymous accessible content.

@romain  and / or @rporchetto  please feel free to contact me so I show my use case with a real example.
