infra-journal-remote: Skip playbook on empty emtpy log_hosts group

Browse Source 
If the log_hosts group is empty, then the deployment fails with the
following error:

{{ hostvars[groups['log_hosts'][0]]['ansible_host'] }}: list object has no element 0"}

As such, we need to skip the playbook if no hosts are defined in that
group.
