What is funny after this commit is that we wrongly relied on a config
which was written that way:
  http-check expect status 200 string passing
instead of:
  http-check expect status 200
  http-check expect string passing

I first thought about a bad regression even though the documentation
does not allow it, but `string passing` was never evaluated, and so
silently ignored; now things are enforced which is better for us to
see those long standing mistakes ;)
Thanks Christopher!
