Note that when the account move date is empty an exception:
constraint null value is raised during execution of action_move_create() method.

Add force_period_on_date context to always make the period be around the current date.

Note that we send a accounting date in reverse_moves func and
the fill_acocunting_date should use it instead of today date.

Updated the translations.
Executed "black" and "isort".

Simplify the code in the process to iterate on each accdoc one at a time (as we
now have a behavior (cut-off) that depends on journal types).
