fix: stop plex settings hanging when tautulli fails to load

The loading guard required dataTautulli but only checked the Plex error, so a failed Tautulli
request would leave the spinner up indefinitely in both setup and normal settings. Setup hides the
Tautulli section entirely, so the request is skipped there rather than awaited.
