Missing and incorrect pagination headers in `/repository/commits` response

It looks like there have been issues with pagination headers when making a request for /repository/commits in gitlab.com

• link headers "last" is incorrect, being overwritten by "next" link header
• X-Total, X-Total-Pages headers are also missing from response

I'm aware that repository commits should omit X-Total, X-Total-Pages, and "last" link header for repositories with over 10,000 commits, but the repositories I checked both had under 1,000 commits and were still missing. Has anyone else seen this?
