Phil just reported that the check I added failed miserably
[https://github.com/phil-blain/git/runs/1238660958] in their fork, and the 
entire run would be abandoned. That's totally unintended, and was caused by
a different metadata format for older recorded runs.

Thanks for a quick response to breakage.

Let's work around this particular issue, and then make the entire check a
lot more robust.

This patch series is based on js/ci-ghwf-dedup-tests.

Will queue.
