Running `tox-current-env` tests with `--current-env` fails

When I run tox-current-env tests with --current-env then I see many tests to fail:

I found that when I do this:

then all tests pass:

Running tox-current-env tests with --current-env is explicitly not expected to work and this is written in README.

That said, I wonder how removing TOX_WORK_DIR makis it work :/

[mtelka]

It looks like the tox("-e", NATIVE_TOXENV, print_deps_stdout_arg, env=env) call removes .tox/py39/bin in the TOX_WORK_DIR and so all tests executed after this call simply fail. I've no idea why this particular tox() call removes the bin dir while all other tox() calls executed in tox-current-env test suite are okay. Maybe in all other tox() calls there is no TOX_WORK_DIR set?

I know that running tox-current-env tests with --current-env is discouraged, but since it mostly pass I think it is worth trying to make it fully working.

Thank you.
