[FIX] point_of_sale: take into account fiscal position in order list

- Create Tax Exempt fiscal position
- Create Customer with Tax Exempt in fiscal position
- Enable Tax Exempt fiscal position in POS settings
- In POS, set customer to one with Tax Exempt
- Create a sale, apply, payment, validate, and click New Order
- Click magnifying glass to reprint receipt
- Default tax is automatically applied to all past orders/receipts

This occur because:
- in Pos OrderList the total is based on the amount total, and not the
actual amount paid
- the fiscal position object is not present when retrieving the order
via `selectedOrder`
