[Upgrade Assistant] Error in cluster_upgrade test

When I run this test locally I see an error in the output, which I think is worth investigating:

  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 a useEffect cleanup function.
