Not a fan of this replicated logic but didn't want to conflate the errors that may exist passing into another function. Also, finding the index happens twice but we need to find the index to verify that the owner is the controllerReference for the object.
This seems to make sure the only controllerReference is the owner that is passed in because
- Only one ControllerReference (1:1) be present on an object but many OwnerReferences (1:N)
- The index returned verifies that the above owner is in fact the controller reference on the object if the index is greater than -1.

Suggested change
| Expect(controllerutil.SetControllerReference(dep, rs, scheme.Scheme)).ToNot(HaveOccurred()) | |
| Expect(controllerutil.SetControllerReference(dep, rs, scheme.Scheme)).ToNot(HaveOccurred()) | |
| Expect(controllerutil.SetOwnerReference(dep2, rs, scheme.Scheme)).ToNot(HaveOccurred()) |
Wondering if that would add useful coverage. Basically we error out because the owner we want to remove is only owner but not the controller
(which is exactly the case we missed before, I think)

So it exists, but the owner we passed in would still error because it doesn't have the controller == true. Makes sense.
