title: expo app with testing react-native-testing-library and jest-native "has no exported member 'toHaveProp"
body: <p>I'm trying to use jest-native as extra matchers and i'm having an installation problem i think
  ...<br />
  I am on a react-native ts app with expo and here are my versions:</p>
  <ul>
  <li><strong>expo</strong>:&quot;~39.0.0&quot;</li>
  <li><strong>@testing-library/react-native version</strong>:&quot;^7.1.0&quot;</li>
  <li><strong>jest-preset</strong>: 'jest-expo',</li>
  <li><strong>react-native version</strong>:&quot; 63.4 &quot;</li>
  </ul>
  <p>I would like to use it in this way:</p>
  <pre><code>import { toHaveProp } from '@testing-library/jest-native';
  
  expect.extend({ toHaveProp });
  </code></pre>
  <p>But it gives me this error:</p>
  <pre><code>Module '&quot;../../../../../../node_modules/@testing-library/jest-native/extend-expect&quot;' has no exported member 'toHaveProp'.
  </code></pre>
  <p>any idea ?</p>
