[FIX] point_of_sale: Correctly set owner on picking create from POS

Current behavior:
If you create a product tracked by serial number and set an owner on the
product. If you make an order from the PoS with this product, the owner
wouldn't be set correctly on the picking created from the PoS.

Steps to reproduce:
- Create product A, tracked by serial number, storable, and available in
    the PoS.
- Add some quantity of product A with an owner (e.g. "Owner A").
- Create a PoS order with product A.
- Validate the order.
- Close the PoS session, go to the picking created from the PoS order
  there will not be any owner set on the picking.
