[FIX] stock: remove incoming warehouse address from delivery slip

Steps to reproduce:
- Configuration -> Settings -> Activate multi-locations.
- Configuration -> Warehouses -> Three-step delivery.
- Generate a three-step delivery (like through a sale order).
- Select either PICK or PACK pickings.
- Print the delivery slip.
- There is a "warehouse address" field with the customer's adress in it.

It makes little sense to display the current warehouse for internal
transfers, as they keep being in the same warehouse after all.
This doesn't impact inter-warehouse transit as in this case, an outgoing
picking is done from one warehouse to the transit location and an
incoming picking is done from the transit location to the other
warehouse.
In both cases the addresses are correctly displayed and didn't use this
'warehouse address'.
