Update fixtures to account for dep. bump

@bezoerb I've updated to inline-critical 0.0.4 in https://github.com/addyosmani/critical/commit/f971117f69fbd3800fbae664a8ba6a779c701d50 and this PR updates the fixtures to bring the tests back into a passing phase.

If you could, could you review this before it gets merged and I tag a new release?
