I unchecked CQ box, previous roll was reverted. We should investigate why it was
reverted before committing this one.

Rollback CL: https://codereview.chromium.org/111393006/

Thanks a lot. I fixed the infrastructure issue in
https://codereview.chromium.org/103993007. Sadly no try job is going to catch
this error so I am going to commit this manually and watch the CI.
