Remove useless tasks

[edenhaus]

This two task get the image id and register them, but the id's will never be used. As we don't use it, we can remove it

Thanks, this was about checking if there wa update available. I tried getting hash, and then verify after pull if hash changed to see if image was updated, as podman didn't tell if pull updated anything. Perhaps I forgot to finish it. There is nowadays the podman auto update. This is dead stuff indeed.
