title: React Native Deep Link Event Listener Not firing
body: <pre><code>  componentDidMount() {
      Linking.addEventListener('url', event =&gt; 
      this.handleOpenURL(event.url));
      Linking.getInitialURL().then(url =&gt; {
       console.log('url===',url);
       if(url)
        this.handleOpenURL(url);
     });
    }
  </code></pre>
  
  <p>handleOpenUrl is never called if the app is already open and I try to change the deep link Url. If the app is already not open then it opens the app and gets the URL.</p>
