[FIX] stock: wrong company when creating a route

Routes created when creating companie were not set to the correct company.

Steps to reproduce:

- Go to Settings > General settings: Activate Manage Multiple companies.
- Go in Inventory > Configuration>Settings: Click "Manage several Warehouses,
each one composed by several stock location". Click "Advanced routing
of products using rules".
- Go in Settings > Users > Companies: Create new companie "ThisNewCompanie"
- Go in Inventory > Configuration>Routes: Open Routes named ThisNewCompanie.

Bug:

All the routes created automatically by creating the company "ThisNewCompanie" are
not set to the company "ThisNewCompanie". They are set to the company of the logged
user when  "ThisNewCompanie" was created
