Figured out a really easy way to fix this in 4.6.1. You can do it without restarting anything or deleting any profiles!

With Keychain Access and your Xcode project open:

1. In Xcode, open Organizer - "Devices" and select the "team" with the duplicate certificate.
2. Switch to Keychain Access and delete the old duplicate certificate(s). Note: Make sure you turn on "show expired certificates" to not miss any.
3. The certificates will have disappeared from the "team" profile in the Xcode Organizer.
4. Clean project and build.

Hope it helps!
