title: Nativescript/angular2: no provider for applicationRef! error after deployment
body: <p>i'm trying to run a very simple nativescript/angular2 app, it seems to build fine but after the app gets deployed to the android (genymotion) emulator I get the following error message.
  So it seems like angular isn't bootstrapped???  not sure at all why this is...  Any idea what i'm doing wrong?</p>
  
  <p>error message:</p>
