Since 4da8c6ebca, the lot creation when filling a stock move line is
done via the stock quant "pick from" field. We thus don't have the
'active_picking_id' key that was set on lot_id field to check if the
user can create or not new stock lot for a particular picking.
This commit add this context key back on the stock move line one2many
for it to be available at the stock quant creation.
