Bug 17667: Do not modify quantity of the original standing order when a receipt is cancelled

When cancelling a receipt, the quantity of the original order is
increased.

Test plan:
Create a basket, mark is as "standing orders"
Create an order
receive it
cancel the receipt
=> Without this patch the quantity of the original order is 2
=> With this patch applied the quantity it always 1
