Title: Fix freeze when quitting the game during timedemo

When one tries to quit the game (via quit in console) while a timedemo
is running, the game freezes indefinitely while displaying the timedemo
results.
This happens because the MessageBox used for that waits for a an event
normally triggered by a timer - but it seems like that does not happen
anymore during Shutdown()

The fix makes sure that this message box isn't displayed.
