Fix two ad insertion related bugs in DefaultPlaybackSessionManager. 

1. A content session after an ad has been played was not re-marked as active,
   leading to new ad session being marked as active too early.
2. Switching from content to post-roll ended the content session because
   the return value of getAdGroupTimeUs of C.TIME_END_OF_SOURCE was not
   handled. Using the nextAdGroupIndex instead.
