There seems to be a conflict between the `testGatewayConfiguration` `unittest` and the `PaymentResourceFunctionalTest.refundFullPayment` functional test. They both seem to read the same `/apps/apps-config/crs-conf-api-properties.xml` (which I didn't realize would be the case for unittests). If `authnetTestMode` is `true`, the `unittest` fails, whereas if it is `false`, then the functional test fails.
