94485: Fix initialization deadlock when backend is unavailable

Browse Source 
When the REST server can't be found, `getEndpoint` errors out, no request gets sent, which causes `fetchRequest` to never emit.

Because of this the `checkTokenCookie$` effect would get deadlocked and initialization would never complete.
