Using backticks 'templateUrl' Component Medata results in templateName being displayed rather than displaying content #3116

I'm not sure if this is intended behavior or not, but not having seen this behavior documented, here's a heads up.

OS?

Windows 10. version 1511 (OS Build 10586.589)

Versions.

angular-cli: 1.0.0-beta.19-3
node: 4.6.0
os: win32 x64

Repro steps.

1. create a new app with ng. (ng new 'helloworld')
2. run (ng serve) -> page loads and the app works. you see "app works" in the browser.
3. go into the src/app/app.component.ts.
4. change the 'templateUrl' metadata from
   templateUrl: './app.component.html',
   To
   writting backtick because I can't escape it in this editor.
   templateUrl: [backtick]./app.component.html[backtick]
5. reload page or re-run ng serve

Expected result

• the page would still load as it did before

Actual result

• the page shows "./app.component.html" in the browser
• the text 'App works' does not appear.

The log given by the failure.

no error logs in the console

Mention any other details that might be useful.

• It should be noted that using backticks for the "selector" works as expected.
• I have not tested to see if this also fails for "styleUrls" metadata.

In converting my project from systemjs to use angular-cli, this eventually came out as the culprit for downstream issues.

In this screenshot we see the expected result

• "selector" has backticks.
• "templateUrl" has singlequote

In this screenshot we see the observed behavior

• "selector" has singlequote.
• "templateUrl" has backticks
