Fix sending data to newrelic from Wikia Maps (interactive maps)

After we switched to gulp build step and new deploytools plugin the service stopped sending data to New Relic. It seems the small change in `server/app.js` fixes the issue. I also added a little bit more logging to know if new relic was loaded.
I agree but first I'd like to smoke test it. New Relic on their pages suggested loading `newrelic` module ASAP. That's probably why it use to be on the top of our `app.js` file.
