fix: Don't remove pytest container when running with host network mode

Browse Source 
When the container runs with host networking instead of the default bridge, the `$HOSTNAME` / `/etc/hostname` reflects that of the host instead of the container ID , which causes the pytest container to get removed accidentally.

Using a container name instead we can more reliably target the container to avoid removing it, should we need to run with host networking instead.
