Ignore directories containing only `__pycache__` in `test_makefile_test_folders`

[tomasr8]

Feature or enhancement

Proposal:

While working on some tests, sometimes when switching branches I have a leftover __pycache__ directory in an otherwise empty test folder. This can happen for example when converting a test file into its own directory.

test_makefile_test_folders already ignores empty folders and __pycache__ folders separately. I think it'd be nice if it also ignored folders which only contain __pycache__.

cc @sobolevn since you added this test originally :)

Has this already been discussed elsewhere?

This is a minor feature, which does not need previous discussion elsewhere
