Summary

This exposes that asymmetric matchers are not called with this - which IMO is a bug. For now I've stuck a @ts-ignore there, but we should fix it

Asymmetric matchers were not called with matcher context - meaning they didn't have access to this.equals, this.utils etc..

First commit makes TypeScript highlight that as an error, second commit fixes passing this.
