fix(compiler): remove some dead capturing code (#3799)

This is a tiny fix removing dead capturing code. For some reason there's code that tries to capture the parent class of a inflight class in the irrelevant case that we're inside an inflight context. In this case the code is dead because an inflight class within an inflight class generates inlined code.

The PR also adds some coloring improvements to the env printing I used to debug this and fixed a comment related to parent class capturing.
