/**
 * @assertion Future<Isolate> spawnUri(Uri uri, List<String> args, message)
 * Creates and spawns an isolate that runs the code from the library with the specified URI.
 * The isolate starts executing the top-level main function of the library with the given URI.
 * The target main may have one of the four following signatures:
 * main()
 * main(args)
 * main(args, message)
 * When present, the argument message is set to the initial message.
 * When present, the argument args is set to the provided args list.
 * Returns a future that will complete with an Isolate instance.
 * The isolate instance can be used to control the spawned isolate.
 * @description Checks spawning 3 isolates from a single source.
