Fix events with gcode command lists not firing

I've dropped hints about this a few times in email but it still persists!

Events which invoke gcode command lists stopped working after the big re-org several months back.
~~~
events:
  enabled: true
  subscriptions:
  - command:
    - M81
    - M117 OctoPrint ready
    event: Connected
    type: gcode
~~~

The only reason is there's a typo that abends in the logging event.
