Post revisions:

- Always update the revision version when updating post authors.
- Check if revisions have been updated and return early.
- Update the revisions by direct query to avoid resetting post_modified.
- Fix a bug where we may be comparing with an autosave but need to compare with the latest revision.

Fixes #16215.
