[FIX] stock, sale_stock: changed the way the procurements look for a suitable rule => Added a m2o field warehouse_id on procurement.order, procurement.rule and stock.move. There was a problem with MTO products because they weren't following the route of the chosen warehouse at all (since all warehouse were creating their rule in the same route, there was no garantee that the route chosen was included in the warehouse selected on the SO)
