Otherwise we get:
import file mismatch:
imported module 'test_sessions' has this __file__ attribute:
/home/florian/proj/qutebrowser/git/tests/integration/features/test_sessions.py
which is not the same as the test file we want to collect:
/home/florian/proj/qutebrowser/git/tests/unit/misc/test_sessions.py
HINT: remove __pycache__ / .pyc files and/or use a unique basename for your test file modules
