Some XHR implementations (like Firefox WebWorker, react-native and some Android 4.x versions) throw an exception when setting xhr.responseType = 'arraybuffer' when xhr.readyState === 2 (which is perfectly valid, spec-wise). That commit fixes that behaviour by reverting some of the changes from #562 for those implementations. Closes #590
