Can be used to refesh the list of MonoBehaviours on this GameObject while PhotonNetwork.UseRpcMonoBehaviourCache is true.
Set PhotonNetwork.UseRpcMonoBehaviourCache to true to enable the caching. Uses this.GetComponents() to get a list of MonoBehaviours to call RPCs on (potentially). While PhotonNetwork.UseRpcMonoBehaviourCache is false, this method has no effect, because the list is refreshed when a RPC gets called.
