[FIX] mrp: cost of produced quant as total cost of production

Browse Source 
At the end of the production, the cost of produced product should be the total
cost of production (cost of components + worklogs) for real time product.
The previous behaviour was to take the standard price from the product which,
in real time product, is the last purchased price, which is 0 for manufactured
product.
