Fix api_json.log not always reporting the right HTTP status code

See merge request gitlab-org/gitlab-ce!19028

As described in https://github.com/aserafin/grape_logging/issues/45, if
a Grape error is caught by the handlers and a different return code
is returned, then the api_json.log would have a 500 error code
instead of the right value. Inserting the GrapeLogging middleware
after the Grape middleware fixes this problem.
