[FIX] stock: Error when re-installing manufacturing application

Steps to reproduce the bug:
- Install MRP
- Uninstall MRP
- Install MRP

Bug:
An error was raised by sql constraint 'barcode_company_uniq' which ensures that
a barcode for a location is unique per company.
But when uninstalling MRP, some locations such as pbm_loc_id or sam_loc_id are set to
active = False and when re-installing MRP, the function _create_missing_locations tried
to re-create these locations and the sql constraint was raised.
