CGU precache does not begin with following error when clusterversion policy does not include desiredUpdate.version spec. This should not be needed when desiredUpdate.image is already specified. 

As a side note, when both version and image are specified, image should take the priority.

precache starts and succeeds

channel, upstream and desiredUpdate.version should not be required when desiredUpdate.image is specified.
