[FIX] stock: preserve context in scrap wizards
[FIX] stock: preserve context in scrap wizards

Context was overwritten in the wizard warning for insufficient
quantity when trying to scrap a componenent from a MO. This had a
side-effect on the move creation of the scrap where the move was
not linked to the MO, thus ignored by the cost analysis report.
