8.4.1: pytest is failing in `tests/test_linters.py::test_pylint` unit

I'm packaging your module as an rpm package so I'm using the typical PEP517 based build, install and test cycle used on building packages from non-root account.

python3 -sBm build -w --no-isolation
because I'm calling build with --no-isolation I'm using during all processes only locally installed modules
install .whl file in </install/prefix>
run pytest with $PYTHONPATH pointing to sitearch and sitelib inside </install/prefix>
build is performed in env which is cut off from access to the public network (pytest is executed with -m "not network")

Here is pytest output:

```console + PYTHONPATH=/home/tkloczko/rpmbuild/BUILDROOT/python-pylama-8.4.1-2.fc35.x86_64/usr/lib64/python3.8/site-packages:/home/tkloczko/rpmbuild/BUILDROOT/python-pylama-8.4.1-2.fc35.x86_64/usr/lib/python3.8/site-packages + /usr/bin/pytest -ra -m 'not network' -q PYLINTHOME is now '/home/tkloczko/.cache/pylint' but obsolescent '/home/tkloczko/.pylint.d' is found; you can safely remove the latter ==================================================================================== test session starts ==================================================================================== platform linux -- Python 3.8.16, pytest-7.2.2, pluggy-1.0.0 rootdir: /home/tkloczko/rpmbuild/BUILD/pylama-8.4.1, configfile: setup.cfg plugins: pylama-8.4.1 collected 35 items tests/test_config.py ... tests/test_config_toml.py . tests/test_context.py ....... tests/test_core.py ..... tests/test_linters.py ........F ========================================================================================= FAILURES ========================================================================================== ________________________________________________________________________________________ test_pylint ________________________________________________________________________________________ context = .fabric at 0x7f816cfd4ca0> def test_pylint(context): from pylama.lint import LINTERS pylint = LINTERS["pylint"] assert pylint ctx = context() pylint().run_check(ctx) errors = ctx.errors assert errors assert errors[0].number assert errors[0].col == 1 assert not errors[0].message.startswith(errors[0].number) # Test immutable params ctx = context() pylint().run_check(ctx) assert ctx.errors assert not ctx.linters_params ctx = context(args="--pylint-confidence=HIGH --ignore=C") pylint().run_check(ctx) > assert not ctx.errors E assert not [, ] E + where [, ] = .errors tests/test_linters.py:177: AssertionError ================================================================================== short test summary info ================================================================================== FAILED tests/test_linters.py::test_pylint - assert not [,
