[FIX] stock: multi warehouse doesn't setup multi location

Use case to reproduce:
- Create a new db
- Go to warehouse and create a new one.

Expected behavior (same than enable location options from settings):
- Internal location has been enable
- It's possible to create locations

It happens because during the warehouse create call, the multi warehouse
and multi locations groups are set. However `res.config.settings`
contains a hook on `set_values` that enable some views and internal
location. Write directly on the groups won't go throuhg this code.
