Breaks ember new

[NullVoxPopuli]

Initially reported here: https://github.com/emberjs/ember.js/issues/19912

During my testing the following works (after removing ember-cli-terser so I could see errors clearly):

• removing the WelcomePage invocation
  • using components from within the app
  • using components from v1 addons
  • using components from v2 addons (ember-stargate / ember-component-statechart (manage))

I believe this is the likely cause https://github.com/ember-cli/ember-welcome-page/blob/master/addon-main.js#L10

It intentionally removes itself from production builds, so the invocation errors.

is there a way to have a build-time error instead of runtime?
