    Minefield: ignore the clock after we explode
    
    If we attempt a multiclear by clicking on a number location that
    has enough flags and that explodes, we will still get releases
    for the other location around the clicked one, but we must make
    sure they don't start the clock, because nothing is going to
    stop it in the future, and it messes the rest of the view.
