auth client should not throw error `Invalid token specified` on method getAuthorizedData

[Selnapenek]

Use Auth0 client

const auth = Auth.createClient({ strategy: AUTH_STRATEGIES.WEB_AUTH0 });
// and call getAuthorizedData() on any page in the application in the hash of which there is no token
auth.getAuthorizedData();

expected result - no error
