[FIX] sale_stock: propagate SO line sequence to stock moves

The default order of the picking moves generated from a sale order should be the same order as the sale order lines.

Steps to reproduce:
- Create a sale order with several sale lines.
- Change the order of the sale lines.
- Confirm the sale order.
  => The moves of the picking don't maintain same order as set before.
