If cmd and entrypoint not set, don't match them

Hello!
I wanted stop the containers matched only by image name, but can't do this, if I not set cmd in playbook.
This behavior confused me.

If cmd or entrypoint is defined for running container, but not defined in playbook, makes matching behavior as this sample:
