Handle componentWillUnmount

[jondavidjohn]

First, this is a great component, thanks for sharing it!

I'm writing some simple specs using @testing-library/react and I'm getting this warning:

  console.error
    Warning: Can't perform a React state update on an unmounted component. This is a no-op, but it indicates a memory leak in your application. To fix, cancel all subscriptions and asynchronous tasks in the componentWillUnmount method.

In doing some research, it looks like this may be of help => https://www.robinwieruch.de/react-warning-cant-call-setstate-on-an-unmounted-component

Does it look like maybe the component continues to get state updates after it is unmounted?
