Fix NPE's when accessing ReviewItApp from activity

getActivity() in Fragment may return null when the fragment is not
added to an activity. This leads to NPE's when trying to get the
ReviewItApp from the activity from a callback that may be executed
after the fragment was removed from the activity. Use isAdded() to
skip the callback code when the fragment is not added to an activity.
