Fix data team report

We'd made too many assumptions about the ordering of result from GH's API.

No new tests sinc existing code is untested.

At least, I assumed it didn't have tests because the changed function has pragma: no cover, but the build's failing because coverage isn't 100%.

This looks like a sensible change to me.

I think the coverage failure is only happening because there's an actual test failure first. And that's probably because the test data doesn't include the field.name attribute.
