[FIX] stock: destination location on delivery order without partner

If you create a delivery order without partner, its destination location
zone will be set to "Partner Locations / Vendors", which is not correct.
This is due to an error in the onchange_picking_type.

This commit fixes the issue by setting the destination location to
"Partner Locations / Customers". This change has not other implications
more than being consistent.
