So, the obvious next step is to make sure journald isn't holding that 
socket.  That's outside my experience, but I'd imagine that you can:

systemctl disable systemd-journald.service
systemctl stop systemd-journald.service

Then you'll need to restart rsyslog and verify that it owns /dev/log.

Only one process can have a socket open at a time.  Since journald holds 
/dev/log, rsyslog can't, which is why your cron log is empty.

There's no real point in using imjournal if journald isn't running.
