auto incremented wrong tag

[jwodder]

We're trying to set up a repository providing a Python library for working with a certain data schema. The library version and the schema version are separate, and so we decided to tag releases with two sets of tags: tags of the form x.y.z are for library releases, while tags of the form schema-a.b.c are for the first release that implements the given schema version. Unfortunately, for some reason, when we tried releasing with auto moments ago, it picked up the schema-* tags as the tags to increment, leading to all sorts of issues. Here are the GitHub Actions logs; you may have to scroll up to see all of the diagnostic output from auto shipit -vv.

EDIT: On further investigation, it looks like auto didn't actually increment the schema-* tag; it just saw the pre-existing tag and used that for the release.
