[empathy/gnome-2-28] Move destruction of connections from finalize to dispose.

    Move destruction of connections from finalize to dispose.
    
    Code can potentially be run between the dispose and finalize methods. This
    moves the destruction of connections and subsequently outstanding_requests
    into the dispose function so the request callback can't be fired between
    unreffing the EmpathyDispatcher and cancelling the pending request.
