Query incoming payments directly

[wilsonianb]

Instead of incoming payment queries happening within ilp-pay's setupPayment. This will allow the Rafiki backend to include the necessary GNAP access token (#583) in incoming payment requests.

:thinking: A first step can be for the backend to check if the incoming payment to be resolved (the receiver of a quote / outgoing payment) is local to this Rafiki instance, bypassing the need to deal with:

• #583

thinking A first step can be for the backend to check if the incoming payment to be resolved (the receiver of a quote / outgoing payment) is local to this Rafiki instance, bypassing the need to deal with:

* [Request grant at other Open Payments server(s) #583](https://github.com/interledger/rafiki/issues/583)

• #595 queries incoming payments over http even if the payment exists at the same Open Payments server. Adding a check for local incoming payments as suggested above resulted in too much duplicate code.
