fix(catalog): re-install resources in existing installplan

This specifically fixes the scenario where a subscription is deleted and
recreated in a namespace with an additional subscription. When the
subscription of interest is deleted, the associated installplan remains
due to the other subscription's owner reference. Because the existing
installplan manifests match, no additional work is done. This is a
problem if resources that were originally installed have been deleted.

Now after a subscription is recreated, the proper owner references are
re-added onto the install plan as well as all the resources are checked
that they are installed.
