To reproduce:
1. Install pos_discount and pos_coupon.
2. Start a session and add item to the order.
3. Add global discount.
4. Change global discount. Stuck.
This is because in some modules, get_orderlines is overridden. Instead
of returning the original object containing the orderlines, it returns
a different array instance containing the lines. This is the reason the
while loop is stuck. With this change, whether get_orderlines return the
container or a copy, we are sure that it won't be stuck in the for loop.
