"Authentication" error if a favourite job is deleted

[OrangeDog]

If a job that's on your favourites list is deleted, it will return a 404 when being queried.
However, the plug-in treats this as an authentication error and disables all the UI.

It would be better if it just indicated (e.g. by greying out) that single job no longer exists, or automatically removed it from the favourites.
