histedit: add test that an invalid editor doesn't bork client state

We had a report of a situation like this borking a user at Google, but
I can't reproduce it in a test. Let's at least backstop the issue with
a test, so we don't accidentally introduce such a bug...

# Extension to write out fake unsupported records into the merge state
