It would probably make sense to just immediately return false if xhrDesc is falsy...
if (!xhrDesc) return;
this reduces nesting

@DaveMBush , the function canPatchDescriptor will see whether zone.js can patch global object, if return false, zone.js will not patch DOM,XHR, so everything will not in zone. So we have to pick up a global object to try to patch and see the result.

Fix #708,
in jsdom, XMLHttpRequest has no onreadystatechange,
in zone.js canPatchDescriptor logic, zone.js use a fake onreadystatechange descriptor which only have a getter, and XMLHttpRequest will use this one, and prevent set onreadystatechange property.
so we need to use a workable onreadystatechange descriptor in this case.
