The buildpack config doesn't seem to be needed. This would affect review apps, staging, and self-hosting. Also, devDependencies are installed by default during the build: https://devcenter.heroku.com/changelog-items/1376 By removing `NPM_CONFIG_PRODUCTION=false` we allow these to be pruned so they're kept out of the slug. This also has the advantage of creating a test environment in PRs where missing production dependencies will cause things to break. That'd be a good thing!
