Certain notifications may not have a course id or the course may not be available locally. In such cases, the app should gracefully fetch the new app content in the MainActivity or CourseDetailActivity.
Additionally, MainActivity should handle the Home page course which contains the Site News announcements.

#307 partially fixed this issue.
Need to work on site notifications next.
