Test deletes toolbox container

Hello,
running coverage tests with tox I've found that it deleted my toolbox container (and maybe another one, I'm not sure).
I run tests on Fedora Silverblue 42, as my user, outside of any container, running only the step test_container_commit in podman/tests/integration/test_containers.py is enough, with
```
tox -e py -- -k test_container_commit
```
edit: I guess this is working as intended, I found that in podman/tests/integration/test_containers.py the setUp function removes all the running containers before doing anything else.
