/kind bug

What this PR does / why we need it:

For detailed information of in tree plugins' execution order, please see:
// https://github.com/karmada-io/karmada/tree/master/docs/proposals/resource-aggregation-proxy#request-routing

But in fact, I found that if the requested resource is defined in ResourceRegistry but there is no cluster, the query is the resource of the karmada apiserver

apiVersion: search.karmada.io/v1alpha1
kind: ResourceRegistry
metadata:
  name: test
spec:
  resourceSelectors:
  - apiVersion: v1
    kind: Node
  - apiVersion: v1
    kind: Pod
  - apiVersion: v1
    kind: Namespace

This will cause two problems

case1.When there is no cluster registered, the query resource comes from karmada-apiserver

case2.When using watch, after deleting all clusters, watch will fail

Which issue(s) this PR fixes:

Hi @yanfeng1992, can you help add the release note? Maybe we need to cherry-pick this patch to the previous branch.
