Clear remove idle timer after destroyAllNow

This keeps track of the remove idle timer and will clear the timer
when destroyAllNow is called, as after all clients are destroyed
there is no need to check for idle clients any longer. Without
clearing the timer, a program may have called destroyAllNow because
it was about to exit, but if the remove idle timer still exists,
the event loop will continue running until at most realIntervalMillis.
