TIPI has no concept of a transaction_id and our main user (lingo
application in combo) use only order_id. PaymentResponse documentation
should be changed to deprecate transaction_id, and first return value of
.request() should be renamed order_id to make things understandable as
with all backend what you get in PaymentResponse.order_id is what is
returned by backend.request()[0].
