feat(web): use session from setSession() for realtime

At the moment, if a cookie isn't set, only the local storage cookie fallback is used for realtime authentication. This means sessions using client.setSession() will be unauthenticated when using realtime.

This PR makes realtime use this.config.session (which is set with client.setSession()) if it exists.
