    manager: don't clear the active log ref immediately on close
    
    We were clearing the (possibly) last reference to a LogviewLog on close,
    but did not also clear out the priv->active_log pointer.
    Since also in case a log is closed we still want the active-changed
    signal to be emitted with the old log pointer as parameter, don't clear
    that ref and keep the internal state consistent. It will be cleared by
    the next call to logview_manager_set_active_log().
