Added functionality for payment to be added to order

[nicholas-davison]

Order class update method was attempting to save order payment type as a string. Corrected to add payment type as an instance of Payment.

Changes

• Changed order.payment_type to be equal to Payment.objects.get(pk=request.data["payment_type"])
