feat(@schematics/angular): remove test.ts file from new projects

The test.ts is now included in `@angular-devkit/build-angular` and unless this needs to be customized is no longer needed to be provided.

Default config:
```js
// This file is required by karma.conf.js and loads recursively all the .spec and framework files
import { getTestBed } from '@angular/core/testing';
import {
  BrowserDynamicTestingModule,
  platformBrowserDynamicTesting
} from '@angular/platform-browser-dynamic/testing';

// First, initialize the Angular testing environment.
getTestBed().initTestEnvironment(BrowserDynamicTestingModule, platformBrowserDynamicTesting(), {
  errorOnUnknownElements: true,
  errorOnUnknownProperties: true
});
```
