Let WP_Error implement WP_JSON_ResponseInterface

@rmccue is there anything still to address here now that #154 was merged?

@rmccue is there anything still to address here now that #154 was merged?

When we start on core integration, I'd like to consider this possibility then. Not something we can do before then really though. :)

@rmccue I don't think this is still applicable?

[rmccue]

I think our is_error and as_error methods on the response object handle this pretty well now. Someday down the line, it'd be nice for is_wp_error to recognise ( $e instanceof WP_REST_Response ) && $e->is_error, but no need to keep this in the meantime I think.

I agree.
