There is a code pattern in l10n modules to create a post init hook method `load_translations` in `__init__.py` and to add it in the `post_init_hook` of the module manifest. For the modules part of this revision, the method `load_translations` was created as expected, but then was missing in the `post_init_hook` key of the manifest, therefore leading to the fact this `load_translations` method was never called for these modules, despite their `spoken_languages` were correctly set in their charf of account template. closes odoo/odoo#108254 Related: odoo/design-themes#631 Related: odoo/enterprise#35084 Related: odoo/upgrade#4144 Signed-off-by: Christophe Simonis <chs@odoo.com>
