[FIX] stock: missing picking type

- Activate 'Lots & Serial Numbers'
- Create a stockable product A, enable tracking 'By Lots'
- From the menu Inventory > Operations > Transfers, create a picking:
Set a picking type
One line of A

It is not possible to set the lot number to validate the transfer.

When creating a picking from the menu, the context key
`default_picking_type_id` is not set. Therefore, the field
`picking_type_id` is empty on the `stock.move`.

We can fall back on the `picking_type_id` of the picking.
