    calendar: Don't allow event messages to be closed
    
    The built-in calendar isn't meant to replace a full-fledged calendar
    app, which is why clearing event messages only hides the event in
    gnome-shell rather than deleting the actual event. This has turned out
    to not be overly useful and often confusing - it creates a discrepancy
    with visible events in apps, isn't revertible in a non-obscure fashion
    and non-obviously limited to the current date.
    
    As we are considering moving events out of the message list and back to
    the calendar, it looks like a good time to remove that ability and keep
    notifications as the only removable messages.
