Aside from a lot of whitespace noise (because
civilint), this changes the policy for updating managed records:
Update: always would override any user changes. That's frustrating when you want to alter the label of something.

Update: unmodified respects user changes.
Cleanup: always ensures the extension can be completely uninstalled.
