title: VSCode Intellisense does not work with webpack + alias
body: <p>I have a project using babel alias:</p>
  
  <pre><code>resolve: {
    alias: {
        vue: 'vue/dist/vue.js',
        '@cmp': resolve('src/components'),
        '@service': resolve('src/services'),
        '@scss': resolve('src/assets/styles'),
    }
  }
  </code></pre>
  
  <p>and a component with:</p>
  
  <pre><code>import someService from '@service/some'
  </code></pre>
  
  <p>And the Intellisense does not work.
  with:</p>
  
  <pre><code>import someService from '../../../../service/some'
  </code></pre>
  
  <p>It does.</p>
  
  <p>Any suggestions?</p>
