Fix history.listen triggered by initial page load on some old browsers

[yangmingshan]

Popstate event will fire after initial page load on some old browsers, like Safari on iOS 9. It will trigger history.listen.

This PR is a hack to fix this problem, the solution is from page.js. I tested on iOS 9, it worked.

I don't know why the Travis CI always timeout 😔

Thanks for the PR, @yangmingshan. Is this code lifted directly from page.js? If so, I'd like to include a comment that tells people where we got it so we give attribution where it's due.

Would you mind rebasing on top of the current master?

[yangmingshan]

Rebased. And yes, this code is from page.js, you can find in here.

How I get the testing pass, is there something wrong？

[yangmingshan]

The solution source information added.

What's the status here? today I run into the same problem.

[yangmingshan]

@mjackson Can you look at it? It's been a long time.

[mjackson]

Sorry for the delay here. This will be released in 4.10.

Hi @yangmingshan, I merged this but it causes one of our tests to fail on Firefox. You can see the failure here: https://travis-ci.org/ReactTraining/history/jobs/583498880

I'm going to revert the commit for now, but I'd be open to trying again if you can figure out what's going wrong in Firefox. Thanks!
