or an accounting document.
Updated the translations.

Specifics to play better with accounting changes:

* No longer change the base ``date`` field; add ``accounting_date`` instead.
* Build periods when loading accounting data for a new company.

 in tests, copy an existing product rather than creating a new one to avoid problems with new required fields in other modules
and also  remove description from manifest as README.rst will be used automatically instead

The copy of a transaction_date should be disabled by default.

Updated the translations.
Updated the unit tests.

Same as Odoo 8 ones.

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.

Remove a "special" field & rename an action.

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