[Nut-upsuser] Dummy-ups cycles between online and onbatt every 5 minutes. (Nut 2.8.0)

Now that upsstats.cgi works, I've noticed that dummy-ups changes state every
5 minutes between OL and OB (probably when the 300 second timer expires). The
UPS state stays online.
Also "online" and "onbatt" are broadcast to the console
probably via WALL. (The state changes don't seem to be form the ups as
upsshed-cmd doesn't run).   Upssched-cmd does run when the UPS is actually
unplugged and plugged back in.
It happens on two different installation.

See attached screenshot and configuration.

This is a part of the heartbeat intended to assure that communication between 
upsd and upsmon is effective.  No UPS is involved.  Every 600 seconds an 11 
minute timer is reset before it runs out.  If it were to run out, the 
installation is broken. See https://rogerprice.org/NUT/ConfigExamples.A5.pdf for
gory detail.

The heartbeat doesn't need this.  It's just noise.

Normal.  The heartbeat doesn't involve any specific UPS.
> Upssched-cmd does run when the UPS is actually unplugged and plugged back
in.
That's because a real UPS in involved.
