Code review comment for lp:~sylvain-legal/openupgrade-server/7.0_update-readthedocs_update_coverage

I'm on Sylvain's side here: It's an interesting piece of information if there actually was no change or if it's just changes we don't need to upgrade. So even if irrelevant to the business of writing migration script (there both mean 'no need to look at that one'), we should keep that in my opinion
