fix: apply included function with arguments instead of app
fix: apply included function with arguments instead of app

This is the "recommended" way as seen in https://ember-cli.com/extending/#addon-entry-point .

I'm opening this PR as `this._super.included(app)` it causes some issues with ember-decorators and the next ember-cli-typescript version. 
This will prevent others from having to dive in on why this happens if you try to port your addon to use these addons.
