We need to be able to see the future without auto planned orders, else how are we going to update them?

erp5_mrp: Copy price_currency to Manufacturing Execution and Production Packing List (PSA specific?).

In PSA for ME: Problem Report is created from a ME which then build a Returned
IPL from scratch copying properties from the ME. After this Returned IPL is
root-expanded, Real Time Inventory Accounting Rule is expanded too and requires
price_currency.

This also avoids KeyError exceptions when Activities have already been processed
in the meantime.

In contrary to the ParentDeliveryPropertyMovementGroup for property, it has
never actually checked the parent Delivery but the current one.

As a matter of fact immediateReindexObject doesn't call reindexObject on the object

buidler: Add tmp fix/workaround on movement order

builder: Use periodicity to determinate start date

builder mixin: Take into account supply date range before create movement

builder: Hackish immediate reindex of order to work for parallel build

builder: use dedicated script to evaluate min stock

builder: autoPlan only if possible

builder: Reference of order line is reference of resource line

builder: include order delay and effective date

builder: fixup add missing part for effective date

builder: Tweak and fix supply builder

builder: Fixup supply builder

builder: immediate reindex delivery on creation

builder: use _edit on delivery to only reindex modification

builder: Supply builder work with period

builder: Supply builder improved

builder: use flow unit for min stock calculation

builder:  Supply Builder Fix future inventory for parts not activated yet

builder: Supply builder do not create movement for resources that won't be consumed in the future

SimulationTool: getNextAlertInventoryDate can look for the lowest invetory inferior to the reference quantity

Update relation field input value only on demand,
changing the state of a relation_input gadget with value_text = ""
now updates the field.

You can reproduce by doing :
- open an object in tab "View" with a relation field (eg my_successor_title) filled
- open a new tab, and edit the field to make it empty
- from the first tab, refresh the view by click on the left panel "View" tab
- the relation field should be emptied.

Prevent "cannot read property of undefined" errors on the JS side.
