    Handle ownership of TpContact.connection automatically.
    
    It recently changed in telepathy-glib and/or Vala 0.14.x finally detected that
    the TpContact.connection property returns an owned TpConnection (making our use
    of "unowned Connection connection = contact.connection" invalid).
