[FIX] mrp: preserve bom lines order within produce wizard

BOM Lines are ordered by a sequence field,
the "handle" widget makes even possible the lines reordering.
The order was respected within the mrp.production
(in o2m products to consume and consumed products)
but not within the mrp.product.produce wizard
