Production builds break with ember-data

[jdurand]

When building a production build that includes ember-data, the build breaks and an error is thrown in the JS console. This happens with any production build once ember-electron & ember-data are packaged together.

Steps to reproduce :

• git clone https://github.com/jdurand/ember-electron-ember-data-issue.git
• cd ember-electron-ember-data-issue
• npm i && ember electron:package -e production
• open electron-out/ember-electron-issue-darwin-x64/ember-electron-issue.app

In the console, you should get something like Uncaught ReferrenceError: a22500 is not defined

Note that if you either npm uninstall ember-data or package in development ember electron:package -e development this error is not thrown.

I'm closing this as this seems to be an issue with Uglify's unused rule (more here: ember-cli/ember-cli#7526 (comment))
