[FIX] purchase_mrp: filter cancelled moves when evaluating kit

The current behaviour does not filter the cancelled moves when
evaluating if the product of the purchase order line is a kit.
This causes that, in cases where you have a cancelled wrong receipt
where the product was being received as a kit, if a new receipt is
created without receiving as a kit Odoo will always expect it as a kit.

After the fix, the cancelled moves will not be considered, as this is what
should be expected from cancelled operations.
