Manage outsourcing services without price
We allow purchasing lines with 0 amount. So when the shipment arrives, we can use the unit price for the invoice.
But when this is used in conjunction with production_outsoursing
the price computed at the get_cost
only use the purchase_line.amount
so have 0 cost.
We should allow updating the price after it's processed, we find in a lot of scenarios where they outsource without knowing the price.
