Connor McEwen b8ff6212f8 bind this in onreadystatechange call
Summary:
I ran into this problem that `this` is undefined in `onreadystatechange` function calls while using this github api library: https://github.com/michael/github/blob/master/github.js#L72

It seems that in the browser, the `onreadystatechange` function expects `this` to be bound. This example on the xhr spec website can be seen using `this` similarly: https://xhr.spec.whatwg.org/#the-getresponseheader()-method
Closes https://github.com/facebook/react-native/pull/5373
