[FIX] stock: set location as replenishment posible without warehouse

Steps to reproduce:

- Install purchase, inventory and manufacturing.
- Now create a subcontractor, with it's corresponding location, it's set
by default.
- Go to this new location and set it as replenishment location.
- Now create a Request for Quotation using this subcontractor.
- We will receive a traceback whent trying to access replenishment.

Issue:

We got a traceback caused by the fact that we are trying to set
as replenishment location, a location that doesn't have a warehouse.

Solution:

We need to add the handling of this case, so we won't always need
a warehouse for the orderpoint.
