    Remove the weak_object parameter when requesting channels.
    
    Use the EmpathyDispatcher pointed to in the DispatcherRequestData instead of
    the weak_object. Outstanding channel requests were being cancelled in the
    EmpathyDispatcher's finalize method. This had the potential to double-cancel
    the requests when the weak_object (EmpathyDispatcher) was unreffed, causing a
    segmentation fault.
