Not receiving payload on iOS for UA Push Messages

This is a classic application (Ti 3.1.3.GA; ti.urbanairship module 3.0.0) that pretty much uses the example code provided on Github. The app appears to register fine, the phone receives the message and brings the app to the front.

The following lines should return the data entered in the "Optional Settings" portion of the UA interface.

Ti.API.info('  Message: ' + e.data.alert);
Ti.API.info('  Payload: ' + e.data.aps);
Ti.API.info('  Target: ' + e.data.aps.target);
