[FIX] stock: Delivery Slip

- Create a picking to deliver 10 units, save
- Edit and change to 12 units
- Print the Delivery Slip => the qty is 10
- Validate the picking with 12 units
- Print the Delivery Slip => the qty is still 10

The use of `ordered_qty` is misleading, since it corresponds to the qty
ordered at creation.
