Mock websockets and assert complex websocket interactions with Jest

/**
 * A simple compatibility method for react's "act".
 * If @testing-library/react is already installed, we just use
 * their implementation - it's complete and has useful warnings.
 * If @testing-library/react is *not* installed, then we just assume
 * that the user is not testing a react application, and use a noop instead.
