Fix couchrest missing the first change (#5452)

CouchRest::Streamer will ignore the first line from a stream. Normally that's the line opening the results array. But for continuous feeds couch will start streaming the array elements right away. So we miss the first one.

There's a pull request pending for couchrest here:
https://github.com/couchrest/couchrest/pull/104

Until it's merged we'll monkeypatch.

Also stopping tapicero again after travis run.
