Make `Stream.take(0)` still listen and close the stream.

It shouldn't matter, but for some streams (e.g., a `ReceivePort`)
it does make a big difference whether it's closed or not.
We can't make a port not keep the isolate alive unless it has been listened to.
If we could, this wouldn't be necessary.
