[FIX] purchase: deletion of PO lines in states other than approved/done

This is related to revision 65d7cc524d9f3a5dc833cb483ccaaf86fab4819d

The `order_line` field of `purchase.order` is readonly within states
aprroved, done. See the field definition. This means it should be
possible to remove lines of a `purchase.order` when the PO is in
any other state than approved or done.

Therefore, the deletion of lines shouldn't be prevented
when the PO is not in state approved or done
