Paul Holzinger f1c68b79eb add hostname to network alias
We use the name as alias but using the hostname makes also sense and
this is what docker does. We have to keep the short id as well for
docker compat.

While adding some tests I removed some duplicated tests that were
executed twice for nv for no reason.

Fixes #17370
