should only show single message on top right when the phase is changed

1. login and register for an SRM
2. when a phase changes, e.g. from intermission to challenge, observe the top right

expected: it should show a single message which tells the current change.

actual: it will show some other messages which are unread before. And there are duplicate messages (the bottom two).

See screenshot.
