[FIX] stock: Wrong error when you work with lot owner

When a stock move was created in a picking with a product set with
a unique serial number existing in the stock of a specific owner.
If the owner was not specified for the stock move then a wrong message
was raised "The serial number 00005 is already in stock.". But the real
problem could come from function quants_get_preferred_domain which didn't
find the existing quant due to the fact that the system didn't check in the
right stock(owner). A new quant was then created with the existing serial number.
And a wrong message was raised.
