403 response from Spotify not fully handling the logout

[zembrodt]

When the Spotify API responds with a non successful and non-401 response (such as 403), the Showtunes app "logs out" and deletes the auth token, but the app stays frozen and doesn't reflect the new logged out state

There could be a check here for the 403 case where it's a single failure but the token still works. Need to do some more investigating, but if the token still works after failure, then on a 403 response we could do a simple API call with the auth token to see if it's still valid, then re-do the request (in the interceptor).
Otherwise, we'll need to logout the user and retrieve a new auth token.
