Fixes the navigation inside the app when led there through deep links.
ALL_COURSES, MY_COURSES, NEWS: Pressing back after a deeplink left a blank screen. Fixed by also finishing the app when there is only one backstack item (the initial blank activity screen).
Course deeplinks: Navigating up and back closed the app because of a missing backstack. Back keeps this behavior but on up navigation, the MainActivity is now started.
I discovered #269 but left it to the future as it is also ViewPager-related and might introduce bugs.
