Without it, pm2 resurrects the list as it was the last time somebody happened to
run `pm2 save` — so a machine that reboots comes back without the site, and with
nothing to indicate anything was meant to be there. The systemd unit is enabled
on this host, so the resurrect definitely happens; the only question was what it
would restore.
After stopping too, not only after starting. The dump has to match reality in
both directions: a server stopped here and left in the dump comes back on its
own at the next reboot, which is the same bug pointing the other way.
A failed save does not fail the action — the process is already started or
stopped by then, and reporting "could not start" about something that did start
is worse than a line saying the list was not persisted. It is in the console
either way.
