Log user out if accessToken is expired

The accessToken & user information is saved in the local storage. We know when it expires, we just have to check on initial load and if expired, log the user out.

Actually, I think it would be better to only check if it's expired on a request that needs authentication. That way if the user visits and only does non-authenticated activities, they're not forced to log in again.

We could use a middleware around the API requests that checks the status of the token, and logs out if expired. Basically iterating in the ideas expressed here
