validate function not doing anything

I believe that the validate function is only run if the token has been verified as having your signature (this is due to hapi-auth-jwt2 authenticating under the hood), so I think token will always exist. i.e. the "if (!token)" branch won't run.

The validate function could do some checks on the info in the token, e.g. check who the user is or something similar.
