currentSession doesn't check if token is still valid on Solid server.

[jairo-campos-JD]

Current Functionality: tracksession check if there is a token in the local storage to validate if the user is logging or not.

Possible issue: Apps doesn't know when the token is invalid to redirect the user to log in. We could use 401 response to fix it but we couldn't make a difference between a token or permissions error.

Solution: New functionality to check if the current session(token) is valid on Solid server and make differences when there is an error for permissions or token.

Technically currentSession of webid-oidc.js.

Main problem is that token renewal is not implemented in the OIDC libraries we use.

Interested in this too!

I'm not sure, but token renewal is here where there is no token on the client and we need to get a new one from the servern right?

What if there is still a token on the client but it's not valid anymore on the server? Can we check that?
