A refresh shouldn't be necessary. If autocomplete results reflect stale data, that's a bug.
I tried reproducing the problem on our current 4.x build, but couldn't. I tried editing a contact's email address, removing one of its addresses, and adding one, and autocomplete kept up with the changes.
It's possible that it's been fixed between your build and the latest one, or that I'm not taking the right steps to reproduce it. If your scenario is different from what I was trying, let us know.
