/**
 * Used to sanitize the first `listener` config.
 *
 * <p>It will:
 * <ul>
 *    <li>resolve any auto-port assignment to the actual port the server is listening on</li>
 *    <li>potentially, replace the host with localhost. This can be useful where the first
 *    listener is a wildcard address, e.g. {@code 0.0.0.0}/li>
 * </ul>
 *
 * @param listener the URL to sanitize
 * @param portResolver the function to call to resolve the port.
 * @param replaceHost flag indicating if the host in the URL should be replaced with localhost.
 * @return the sanitized URL.
