Test case

push/replaceState() during load followed by a history.back() doesn't work as
expected.

According to 10.5.3 of the spec
(http://dev.w3.org/html5/spec/Overview.html#activating-state-object-entries),
if a state object is popped before the document has loaded, that popped state
object becomes the "pending" state object and the event is to-be-fired after
the load event fires.

I thought I had this working originally when working on the ajaxy history
stuff, but apparently missed it in the end.  

See the attached test case.

The output is:
Pushing state - document.readyState is loading
Popping state - document.readyState is loading
State popped - null (type object) - document.readyState is complete

And I'd expect it to be:
Pushing state - document.readyState is loading
Popping state - document.readyState is loading
Load event fired - document.readyState is complete
State popped - New state (type string) - document.readyState is complete
