    Populate context roles when using stored context

    Currently we leave the context roles empty when loading the stored
    context, even though there are roles associated with e.g the trust
    scoped token used via loading the stored context. Loading the auth
    ref and populating the roles from the token ensure any RBAC performed
    on the context roles will work as expected.
