fix: Avoid recursion if a class has a reference to itself.

[matthewwardrop]

I was attempting to use mkdocstrings with some Python library I maintain, only to find it failed because one of the classes referred to itself in one of its members. I'm not sure if this fix is ideal (since it omits the member entirely rather than including it but making it clear that there is a self-reference involved; and it doesn't deal with with non-local recursion).

What are your thoughts?

I think this fix is good enough for now. It's getting harder and harder to get the logic right. I must work on a refactor that takes all this cases into account, or at least make it easy to fix things like this when they hit.

Thanks @pawamoy ! And yeah, these projects often have a way of outgrowing themselves... But great work so far!

You put my mind at ease a bit, thank you so much 😅
