[IMP] stock, mrp: remove MTO route magical behavior

When a move is created from a location A to a location B and not
via a rule but it wants to apply the rule logic in order to know
if a move is MTS or MTO then _adjust_procure_method is called.

It will check if a rule between A and B for the selected product/
category/warehouse and if it exists it will apply the rule procure
method to the move. If not it will check if the route MTO is ticked,
and will set the move as MTO even if no rule exist. It could be
miss understanding by the user that have moves MTO without matching
rule. It would be easier to have a single proccess with rule.
