Title: Revert "Merge pull request #2390 from phptek/2389"

The original change stops you from being able to add yourself to a relation.

I've reverted it locally and been unable to reproduce the error it's fixing. Assuming there is an actual problem with circular references, I'm still thinking that this should be reverted and the actual problem fixed rather than just hiding it.
