[FIX] sale_management: fix pricelist computation for optional products

1. Have a product with cost A
2. Have a pricelist which modify the price of the product to B based on
the quantity
3. Create a sale order with the pricelist. Under the "Optional
Products" tab add the product and match the pricelist requirements

No price modification will occur, because there is no reaction to the
quantity change
