title: Angular schematic is not creating files from templates
body: <p>I've created an angular schematic for the purposes of creating boilerplate code with an ng generate command, however despite all the articles I've read through and messing about, I cannot get the files to create.</p>
  
  <p><strong>I've the following code in my schematic factory:</strong></p>
  
  <pre><code>export function createComponent(_options: any): Rule {
      return (tree: Tree, _context: SchematicContext) =&gt; {
          setupOptions(tree, _options);
  
          const movePath = normalize(_options.path + '/' + strings.dasherize(_options.name));
  
          const templateSource = apply(url('./files'), [
              template({
                  ...strings,
                  ..._options,
              }),
              move(movePath)
          ]);
  
          return mergeWith(templateSource);
      };
  }
  </code></pre>
  
  <p>In the same directory as this is a files directory containing my "__name@dasherize__.component.ts" template which I'm expecting to get pulled in as part of the url('./files') function but I'm not sure this is happening. </p>
  
  <p><strong>My template file is as follows:</strong></p>
  
  <pre><code>import { Component } from '@angular/core';
  
  @Component({
      selector: 'wx-&lt;%= dasherize(componentName) %&gt;'
  })
  export class &lt;%= classify(componentName) %&gt;Component {
  
  }
  </code></pre>
  
  <p>I'd expect a 'CREATE'  to appear when I run the schematic but all I get is 'Nothing to be done.'</p>
  
  <p>Oddly enough using tree.create() is successfully running to create files so I wonder if the url() or apply() functions are not running as expected.</p>
