    chatView: Don't insert pending message multiple times
    
    The 'notify::channel' handler assumes that the signal is only
    emitted on actual property changes. However this assumption is
    wrong, as the property is set via g_object_set_property() which
    will always notify. So handle notifies without a value change
    by filtering out pending messages that have already been inserted
    previously.
