addEventListener has issues with a null callback

[alxhub]

Uncaught TypeError: Cannot read property 'toString' of null
obj.addEventListener @ angular2.dev.js:1068
Gestures.add @ polymer.html:752

Polymer adds a null listener to the 'tap' event on document (something about enabling document-wide listeners):

// enable document-wide tap recognizer
if (event === 'tap') {
  Polymer.Gestures.add(document, 'tap', null);
}

Unfortunately zone.js's addEventListener has issues with a null callback, and throws a few exceptions (calling toString() on the callback and trying to set properties on it).

The last commit in master tries to fix this issue... but in the wrong way as we only do not delegate to the original add/remove function when the handled is null. It should be fixed before next zone release.

@Brooooooklyn any chance you can give this issue a look ?

Running into exact this issue, but can't update as (AFAIK) my jspm only knows v0.5.8. Any idea when the next version is released?
