title: Find element by id in react-testing-library
body: <p>I'm using <a href="https://github.com/kentcdodds/react-testing-library" rel="noreferrer">react-testing-libarary</a> to test my react application. For some reason, I need to be able to find the element by <code>id</code> and not <code>data-testid</code>. There is no way to achieve this in the documentation.</p>
  
  <p>Is there a way to achieve this?</p>
  
  <p>I've the rendered output as:</p>
  
  <pre><code>const dom = render(&lt;App /&gt;);
  </code></pre>
  
  <p>I'm looking for something in line of:</p>
  
  <pre><code>const input = dom.getElemenById('firstinput');
  //or 
  const input = dom.getById('firstinput');
  </code></pre>
