CDN link causing CORS errors

Rollbar's cloudfront link is now permanently redirected to a cdnjs cloudflare link(see screenshot). This is causing CORS errors in our app.

Relevant info on CORS w/ redirects

We are now using this fork: https://github.com/paulcwatts/ember-cli-rollbar
that fixes that.
