[FIX] point_of_sale: correctly set owner on pos order refund

Current behavior:
If set an owner on a product and make a pos order with this product then
refund this order. The owner would be lost on the refund.

Steps to reproduce:
- Activate the consignment feature
- Create a product, and add some stock with a owner (e.g. "John Doe")
- Create a pos order with this product
- Refund the pos order
- Go to the stock picking of the refund, the owner is not set on the
  move lines.
