Code completion not working after `...` (spread)

[jwren]

No completions from the Analysis Server at the |:

void main() async {
  final list1 = [1, 2, 3];

  final list2 = [0, ...li|];

  print(list2);
}

There is a couple of other cases when completion does not work perfectly, even with this CL.

1. No completion for the loop variable in IfElement, e.g. no name in [for (var name in names) ^].
2. No else completion in IfElement.

We decided it's not necessary to try to cherry-pick a fix into Dart 2.3.

Did this change land already?

Yes, see the dart-bot message just above.

But #36733 (comment) is not addresses yet.
