Use all moves to compute FIFO
product_cost_fifo: Use all moves to compute FIFO
We must consider any incoming moves (ex: inventory) for the computation of the
FIFO otherwise the back computation to find first in moves does not pick enough
moves. As not all incoming moves have a unit price, we use the current cost
price as fallback.
Also in re-computation, the in or out move test should only rely on the storage
location usage in order to properly compute the average cost.
