Not writing user-installed search engines in the old format is an intended change. I know it can cause minor inconvenience for users moving back and forth between 2 releases, but I don't think it's worth attempting to fix (it's not the end of the world to have to install an engine again in this edge case).

While working on bug 1203167, I ensured that if someone uses Fx44, then upgrades to 45, and then downgrades to 44, all the settings that had been set in Firefox 44 are still available in Firefox 44 (and they are also migrated to Firefox 45 of course). However, if someone changes search settings in Firefox 45, Firefox 44 won't be able to see them.
