Fix using signaling settings while being refetched

When the external signaling server returns the error "token_expired" the
signaling settings are fetched again. However, if there are further
requests and "token_expired" is returned again the previous fetch is
canceled and a new one started instead, which causes the settings to be
temporary set to "null".
