Disabling the result section of an alias still calls chatops.post_result which fails

cat alias_ping.yaml

name: "ping"
action_ref: "ec.host_pingable"
description: "Check if machine is pingable"
formats:
  - "ping {{server}}"
ack:
  enabled: false
result:
  enabled: false

Traceback (most recent call last):
  File "/opt/stackstorm/st2/local/lib/python2.7/site-packages/st2actions/runners/python_action_wrapper.py", line 179, in <module>
    obj.run()
  File "/opt/stackstorm/st2/local/lib/python2.7/site-packages/st2actions/runners/python_action_wrapper.py", line 116, in run
    output = action.run(**self._parameters)
  File "/opt/stackstorm/packs/chatops/actions/format_execution_result.py", line 42, in run
    raise Exception("Output of this template is disabled.")
Exception: Output of this template is disabled.

These expected failures make it difficult to monitor for other actual problems that cause failures.

Thanks
