Fix string comparison when self has accessibility order reference

Summary:
I was informed that we could not reference ourselves with accessibility order when using `useID`. The reason for that ended up being because of this if statement which uses `==`. Note this worked with a normal string like `"foo"` but `useID` has ids like `"<<r0>>"` so I imagine the < and > made this break.
