TypeError: Cannot read property 'router' of undefined

Hello, I just had this error while trying to configure my engine. I just have one route in my addon:

import buildRoutes from 'ember-engines/routes';

export default buildRoutes(function() {
  this.route('myRoute');
});

In my app/router.js

this.mount('myAddon');

I received this error, when I tried to access to this route via _http://localhost:4200/myAddon/myRoute_:

TypeError: Cannot read property 'router' of undefined
  at error (router.js:827)
    at Router$1.triggerEvent (router.js:1006)
    at trigger (router.js:111)

Maybe somebody already faced this error, I couldn find any information on SO or github, but maybe I missed something!

If you need more information, please ask me! Good day to you!

Just done some research. Issue appear when adding ember-simple-auth addon. Prepared test project to reproduce an issue. You can download it here https://www.dropbox.com/s/ikjlltvw40sr4oi/bug_test.tar.gz?dl=0 Engines route protected with ember-simple-auth mixin and it caused an issue. To see it go to http://localhost:4200/blog/ Engine’s route without simeple auth mixin work well.

May be issue not in engines, but in simple-auth. But I hope at least you can check it and give a reasonable reply or may be point me what I am doing wrong.

I submitted https://github.com/emberjs/ember.js/pull/15665 to address the specific issue reported here (the 'router' of undefined error).
