We created an index in the mixin, but the `init` was never called as there was a missing `super` in `account_move_line`. We also remove the index in `sales_project`, as it now is done in the mixin (and we don't want different names for it). closes odoo/odoo#115948 X-original-commit: 98a556031180cf72680b4f082a5c5d7b491742b7 Signed-off-by: William André (wan) <wan@odoo.com>
