baseUrl & paths not working correctly #2634

Please provide us with the following information:

OS?

Windows 10.

Versions.

angular-cli: 1.0.0-beta.17
node: 6.7.0
os: win32 x64

Repro steps.

Updating my app from beta.16 to beta.17, and trying to utilise the new baseUrl & paths configuration in tsconfig.json as follows:

"baseUrl": ".",
 "paths": {
   "@shared/*": [
     "app/shared/*"
   ],

When I use

import { Http } from '@angular/http';
import { StorageService } from '@shared/services';

@Injectable()
export class AuthService {
  constructor(private http: Http, private storageService: StorageService) { ... }
}

typescript and webpack compiles and builds without erros, but I get an error in chrome that says

Can't resolve all parameters for AuthService: (Http, ?)

But if I write:

import { Http } from '@angular/http';
import { StorageService } from './storage.service';

@Injectable()
export class AuthService {
  constructor(private http: Http, private storageService: StorageService) { ... }
}

it works.

AuthService and StorageService are in the same folder app/shared/services/ and there's an index.ts with export * from './storage.service'; in it, so this should work right?

Is there anything more I need to add to tsconfig.json or angular-cli.json to get it to work?
