[FIX] stock: scrap from current picking

Steps to reproduce:

1) Make sure you don't have any piece of the product you're about to
sell on hand.
2) Create two sale order, each with 10 pieces of the product and
validate them
3) Do a RFQ and buy 15 pieces.
4) On the earliest sale order, check the availability, it should
autofill the desired quantity with 10
5) Do the same on the second, it autofills 5.
6) On the later delivery, scrap one.
=> The product is scrapped from the early picking.

Sort the candidates so the current picking is on top, this ensure the
current picking is the first scraped.
