git: use the proper filenode for deleted files in changelog.changelogrevision
Inline printing shows it still doesn't find the removed file in the test, but it
is at least a str instead of bytes like the immediate query before it that does
find files. Looking at the database, it doesn't look like the remove was
recorded. Additionally, `hg log -r 'removes("re:.*")'` stacktraces.
