[QA] Copyvio test still failing

[Jon Robson]

Juliusz's patch [1]  doesn't seem to have fixed the Chrome builds [2].
Chris didn't like Juliusz's patch and submitted a new one [3] which
doesn't work for me either.

I think we should simplify this by
1) reverting Juliusz's change [4]
2) turning off the test for Chrome with my original patch [5] and then
take a look at the bug [6] separately.

Thoughts?
