title: Untrue 'not found' warnings in Angular-CLI/Webpack project
body: <p>I'm getting a bunch of warnings like the following that things cannot be found but they are in the right places and my app runs so the warnings must be wrong. I'm using webpack version 2.1.0-beta.22 and webpack-dev-server              2.1.0-beta.10. My project is on GitHub <a href="https://github.com/dancancro/great-big-angular2-example/blob/master/src/app/core/store/claim/claim.model.ts#L3" rel="noreferrer">here</a> </p>
  
  <p>Do you know how I can fix this? Thanks!</p>
