[IMP] mrp: block usage of duplicate serial number

With this commit, the manufacturer will now be noticed earlier in
the process if he produced/consumed a serial number already produced/consumed in a
previous production. Before this commit, an error was triggered as
well but only at the very last step of the production.
This leaded to two issues :
 - The user had to unlock-edit-lock to update the wrong serial number
 - On large production, it was difficult to figure out which was/were
   the product(s) to fix.

The search on previous production is done each time the produce wizard is closed
or once the production is done on a workorder
