Creating a stock move chain through `action_confirm()` + `run_*()`
sometimes needs to carry data from move to move to specify the future
documents to be created. For instance the supplier to choose to create
purchase order or stock route to filter stock rule to be triggered . The
field `route_ids` on `stock.move` has exactly this meaning. Forcing the
route to have the same company than the stock move may be too strict for
some intercompany flows inside which the route to choose are just saved
for future stock move creation.
