When using `--ensure-unique-name`, don't needlessly append `"-0"` if the container name is already unique. This is especially helpful with NixOps since when it deploys to a container it uses `--ensure-unique-name`. This means that the container name will never match the deployment host due to the `"-0"`. Having the container name and the host name match isn't exactly a requirement, but it's nice to have and a small change.
