In "stock.move" model the fields location_id and location_dest_id
are required. But when disabling "Manage Multiple Locations and Warehouses"
in Technical Settings, these fields became hidden in stock.move.form and
then it was impossible to add an new product to consume in mrp.production.form.
In 8.0, to be in group_stock_user implies to be in stock.group_locations.
