Ensure the first bit of body directly after the headers is emitted into the stream (#68)

* Fix #67 caused by the little bit of body coming with the headers not emitted from the stream but from the response never making it into the stream

* $response should not be emitted here, that will happen again once the data flowed through the stream into the response: #68 (comment)
