Stops working after Polyfill component unmounts

[kowalski]

This happens on Android when app is closed and opened again.
The new React component is created but the global module context holds old reference to worker.

I dont have much time to investigate this, but maybe you can suggest a quick fix.
do you have a suggestion for a fix?
can you point me to the code you think is the source of the issue?

@sirpy I was going to ask a colleage to do a PR @Ofadiman

I think the fix is like

class PolyfillCrypto extends React.Component {
  constructor(props) {
    super(props);
    this.props = props;
    this.webViewRef = React.createRef();
  }

  shouldComponentUpdate() {
    return false;
  }

  componentWillUnmount() {
    resolveWorker = undefined;
+    workerPromise = new Promise((resolve) => {
+      resolveWorker = resolve;
+    });
  }

So basically reset the promise that holds the reference when component is unmounting so that the next one can set the correct reference.
