Firebase storage FirebaseApiNotAvailableException repeatedly in the log when offline

Sorry for the log overload. The first (W/ExponenentialBackoff) needs to be pared down quite a bit (we're planning on better client side logging in the future), while the second (E/StorageUtil) can be prevented by linking Firebase Authentication in the app's build.gradle file:

implementation "com.google.firebase:firebase-auth:16.2.0".
