IndexedDB upgradeNeeded not working in stable Chrome

Consider this code:

  Future<bool> open() {
    Completer completer = new Completer();
    var request = window.indexedDB.open(dbName, version);
    request.on.success.add((e) => _onDbOpened(request.result, completer));
    request.on.error.add(_onError);
    request.on.upgradeNeeded.add((e) => _onUpgradeNeeded(request.transaction));
    return completer.future;
  }

If you compile this to JavaScript and run in Chrome 22, you'll get this error:
 "Uncaught TypeError: Object #<_IDBRequestEventsImpl> has no method 'get$upgradeNeeded' "

Note that our docs show upgradeNeeded as a valid option to use: http://api.dartlang.org/docs/bleeding_edge/dart_html/IDBOpenDBRequestEvents.html

We should polyfill the old setVersion with the new upgradeNeeded.
