http2: statusCode should be a Number

[robertkowalski]

Fixes#118

Issue I have right now: somehow the server / client hangs and does not end the test. req.resume() or req.end() are not called in the http1 implementation in https://github.com/nodejs/http2/blob/master/test/parallel/test-http-write-empty-string.js, so I'm puzzled.

there is a on('data') event https://github.com/nodejs/http2/blob/master/test/parallel/test-http-write-empty-string.js#L47 on the response. http.get() automatically ends the requests.
