Don't rename pod if container has the same name

We enforce the naming scheme "<podname>-<containername>" here [1].
Therefore we must not rename the pod in case of a naming conflict
between pod name and container name. Not renaming the pod increases the
usability for the user and easies scripting based on the name. Otherwise
a user must set some label to reliable find a pod after creation. Or
have to implement the renaming logic in the script.

Fixes #12722
