Description of problem:
When we have a migration plan with PVC conflicts and we execute a State migration the migmigration resource will report a critical condition. The only way to fix this conflict using the UI is by executing a new State migration and mapping the PVCs correctly. If we do so, the result is that the critical condition disappears and the migration is executed twice.


Version-Release number of selected component (if applicable):
SOURCE CLUSTER: AWS OCP 3.11 (MTC 1.5.1) NFS
TARGET CLUSTER: AWS OCP 4.9 (MTC 1.6.0) OCS4

How reproducible:
Always


Steps to Reproduce:
1. Create an namespace with a pvc and a pod mounting the pvc

$ oc new-project ocp-44516-statewarning-ns

$ cat <<EOF | oc create -f -
apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  namespace: ocp-44516-statewarning-ns
  name: test-data
spec:
  accessModes:
  - ReadWriteOnce
  resources:
    requests:
      storage: 1Gi
EOF

$ cat <<EOF | oc create -f -
apiVersion:  apps/v1
kind: Deployment
metadata:
  labels:
    app: state-warning-test
  name: state-warning-test
  namespace: ocp-44516-statewarning-ns
spec:
  replicas:  1
  selector:
    matchLabels:
      app: resize-test
  template:
    metadata:
      labels:
        app: resize-test
    spec:
      containers:
      - name: podtest
        imagePullPolicy: Always
        image: quay.io/openshifttest/alpine
        command: [ "/bin/sh", "-c", "--" ]
        args:
        - while true; do sleep 30; done;
        restartPolicy: Never
        volumeMounts:
        - name: testvolume
          mountPath: /data/test
      volumes:
      - name: testvolume
        persistentVolumeClaim:
          claimName: test-data
EOF


2. Create an intra-cluster migration plan.

3. Execute a "State" migration without mapping anything.

4. Once the Critical condition is reported, execute a new State migration, and now map the PVC to a different PVC name

Actual results:
After mapping the PVC name and fixing the conflict, the critical condition will disappear and the State migration will be executed twice.

Expected results:
There should be a way of using the UI and fix the PVC conflict running this migration only once.
