This is related to rev. a218a9ed3f6c965820f2ebdf76ee0e6c89c59a0c

[FIX] mrp: chain product move and MO locations

When validating a SO containing a `make to stock` + `manufacture` product
(with bom + orderpoint), we have the following stock moves:
* Product move
* Manufacturing order
Selling 1 such product would yield 2 as incoming quantity, an
inconsistency that this commit solves by setting the location_id of the
product move to the MO's location_dest_id (in the same fashion that
the create_pickings method does in an mts/buy case)
