[IMP] stock_picking_batch: ask for qty done and backorder

Previsously picking batch done button automatically run backorder
for picking that need and set a quantity done for picking without it

This commit changes the function done for picking wave in order to
call the needed wizard(set qty_done automatically or asking for a
backorder). Also it override the immediate transfer wizard in order to
pass the picking to backorder found in done function through the process
action.

pick_to_backorder_ids is needed in immediate transfer since we need to
pass the backorders from the done function in stock_picking_batch
through the immediate transfer wizard.
