Remove find_dependent_paths and depenent path cleanup

[zero323]

This PR drops dependent files removal logic from runtest and deletes find_dependent_paths method.

Rationale:

The logic for finding dependent paths is clearly broken at the moment (#83) and clearly does more harm than good.

In general, mypy should be able to identify out-of-date cache items and recompute these with any user intervention, so this functionality should be unnecessary for correctness and serve as a mere optimization to keep cache size under control.

LGTM! Mypy worked differently back in the days 🙂

LGTM!

Thanks @sobolevn

I couldn't say ‒ until now I didn't break anything related to cache :)

The idea of cache cleaning / pruning might be still useful, but ti definitely has to be more subtle and with good test coverage that can show use when something breaks. It is also a subject for discussion if, in the current state of things, cleaning test cache is safe

	if not self.disable_cache:
	for file in self.files:
	path = Path(file.path)
	self.remove_cache_files(path.with_suffix(""))

It doesn't seem to break anything in an obvious way at the moment, but I'll keep poking around and see what comes up ‒ I hope you don't mind reviewing my silly PRs from time to time ;)
