[REF] stock: default warehouse

In a bunch of places, a default warehouse is selected to make an operation:
- default warehouse on a sale order
- default location of an unbuild order
- default location of an inventory adjustment

Before this commit, the warehouse that was created first was always selected.
Now, we introduce a sequence field and a widget handle so that the user can
chose the default one as he wishes.
