[FIX] stock_account: inventory with company

- Set a company on the inventory location
- Create a stockable product, FIFO, real-time, with a cost
- Receive a unit

The product stock value remains zero.

The fact that the inventory location has a company set should not impact
the product cost. This is useful when a scrap location as a company set.

The domain of move selection is incomplete. It should be, for the 'in'
moves:
- coming from a location without company, or an inventory location
  within the same company
- going to a location within the same company

For the 'out' moves:
- coming from to a location within the same company
- going to a location without company, or an inventory location within
  the same company
