Push message from server can cause app to silently upload stored bluetooth/location data

[doug-leith]

Function pushDataToServer() function in FcmMessagingService.java implements functionality whereby receipt of an appropriate push message from the server causes the app to respond by uploading the stored bluetooth/location data to the server. This happens silently, without notifying the user or asking for their consent. We recommend that this functionality be disabled/removed as a matter of urgency.
