A few improvements to return refunds (mainly focused on handling offline payment types):
1. When calculating payments received for an order, now looking at Payment instead of PaymentGatewayResponse; 2. When pulling the PaymentPreferences to refund against, now considering the received status as well as settled; 3. If the PaymentPreference is not electronic or a billing account, now creating a payment with the correct details set instead of creating a "filler" payment (whatever that was) (604811)
