Observed Behavior

Versioned ClusterTasks, ie ClusterTasks with names like`buildah-1-6-0`are getting deleted during an upgrade.

Expected Behavior

Versioned ClusterTasks should remain on a cluster unaffected after an operator upgrade

Reproducer

Not sure how to reproduce it from previous releases or OLM

What we can do is -
1. Spin up the operator with v1.6.0 in deployment
2. there will be clustertask of 1-6-0 suffix and also a installerset for that
3. now add few clusertask with 1-7-0 suffix in ko data
4. spin up the operator again with v1.7.0 in deployment
5. now notice that old installerset is not deleted and clustertasl 1-6-0 are there
6. new installerset created with clustertask 1-7-0
