title: WebStorm hints me the TS error (TS2705) when I use jest(ts-jest async/await test)
body: <p>Packages:

  ts-jest
  @types/jest</p>
  
  <p>IDE:
  WebStorm</p>
  
  <p>When I use the <a href="https://facebook.github.io/jest/docs/en/asynchronous.html#async-await" rel="nofollow noreferrer">jest</a> asynchronous test there is a TS error (TS2705) that I cannot resolve. But this hint does not affect the <code>jest</code> command.</p>

  <p>There is the same error when I use the smallest test:</p>
  
  <pre><code>import {} from 'jest';
  
  test('async test',async ()=&gt;{
  
  });
  </code></pre>

  <pre><code>module.exports =  {
