[gnome-shell] calendar: Remove events section from message list

    calendar: Remove events section from message list
    
    While treating notifications as a type of present event was a neat
    concept, there are some issues with it that we never managed to
    address (not least the inability to "open" an event).
    
    So remove the current events section from the message list; we'll
    bring back events in a different form later.
