[FIX] stock: fix replenishement with archived RR

If some RR is archived and where the a forecasted demand on the
warehouse location, it Replenishement will crash will due to the
SQL constraint. It happens because the archived RR aren't take in
account in `_get_orderpoint_action` and the method will try to
create a orderpoint with same product + location which
lead to trigger the SQL constraint `product_location_check`.

Also avoid filtered in for loop to improve performance and use the
read_group instead.
