Testing components using templateUrl fails with setup from this quickstart

[lars-erik]

I'm leaving an issue here as a companion to this stack overflow question:
http://stackoverflow.com/questions/41243183/karma-fails-to-proxy-html-with-the-angular-2-quickstart-config

Gist of it is that karma reports "failed to proxy [file] (socket hang up)" when I try to use templateUrl in a component. Just changing app.component.ts to the following (and creating the html file under app) will make it fail:

import { Component } from '@angular/core';

@Component({
  selector: 'my-app',
  //template: `<h1>Hello {{name}}</h1>`,
  templateUrl: "app/test.html"
})
export class AppComponent  { name = 'Angular'; }

I'd make a PR, but I'm sure it'll be really quick for anyone who already have a fork. :)
The solution is to add a leading / to the appAssets variable in karma.conf.js.

var appAssets = '/base/app/';

I don't know how we missed. Probably because we no longer use templateUrl's with absolute URLS. Always component-relative. Thanks for finding it. Fixed in PR #351
