No error reporting when service is not matched

About

When creating a ServiceBinding resource with a .spec.service reference that cannot be resolved, the ServiceBinding resource does not set a failure condition and the controller does not include any useful error messages. This seems to happen if it cannot find the resource for any reason, e.g. an incorrect apiVerison/Kind/or Name. This makes it hard to debug the problem.

Looking at the controller logs this is the only error that appears, perhaps it's failing while trying to update the status?

Using this release https://github.com/vmware-labs/service-bindings/releases/download/v0.5.0/service-bindings-0.5.0.yaml

To reproduce

1. Install 0.5.0 kapp deploy -a service-bindings -f https://github.com/vmware-labs/service-bindings/releases/download/v0.5.0/service-bindings-0.5.0.yaml
2. Install the RMQ operator kubectl apply -f https://github.com/rabbitmq/cluster-operator/releases/latest/download/cluster-operator.yml
3. Apply the following YAML - note we have not created the referenced RMQ.

4. Check the binding resource - verify you get no status updated and no updated conditions.

k get servicebinding
NAME          READY   REASON   AGE
rmq-binding                    3m45s
