You can't remove this line. `testacular run` would fail.

I know, the way it's currently implemented is not nice, but until we refactor it, we need to keep this.
(when you do `testacular` run, it appends another adapter, to basically stream the output to the runner https://github.com/testacular/testacular/blob/master/lib/server.js#L164 and https://github.com/testacular/testacular/blob/master/lib/reporters/Multi.js#L9)
