0.8.1 breaks on phantomJS

[paulsouche]

Hi,

I have an issue since this commit on phantomJS 2.2.1.

PhantomJS 2.1.1 (Linux 0.0.0) ERROR
  TypeError: Attempted to assign to readonly property.
  at karma-shim.js:133326
PhantomJS 2.1.1 (Linux 0.0.0) ERROR

Line is here

I think one of the property stack or zoneAwareStack must be readonly but I can't figure out why ? Everything works fine on chrome or when downgrading on 0.8.0.

Thanks

@paulsouche , could you provide a reproduce repo? the code https://github.com/angular/zone.js/blob/master/lib/zone.ts#L1792 not newly added in 0.8.1, so maybe some other logic goes wrong. thanks.

@JiaLiPassion we have several private repositories but you can reproduce with this starter. I've just updated it to have same dependencies.
