[FIX] stock: push in intercompany

It's not possible to push in intercompany location because the warehouse
is set base on the initial move. However in intercompany we don't
have a warehouse in the most cases.

Also there is an issue with the cache holding the route on the product
for the current company. So we invalidate it to retrieve all the routes
among the different companies
