Update ClusterResourceSetBinding owner references

The ClusterResourceSet owner references were being updated due to a
typo. This update was ineffectual, because the ClusterResourceSet object
is not patched after the references are updated.

However, due to a separate bug in RemoveOwnerRef, the
ClusterResourceSetBinding owner references _were_ being updated.
