[FIX] point_of_sale: Correctly set fiscal position on refunded order

Current behavior:
If you apply a fiscal position on a POS order, then refund it, the
fiscal position is not applied on the refund order.

Steps to reproduce:
- Create a fiscal position that match 15% of taxes to 0% of taxes
- Create a POS order with a product that has 15% of taxes
- Apply the fiscal position on the order
- Refund the order
- Check the taxes on the refund order, they are not correct
