helm: Deletion Policy before-hook-creation does not work as expected

The deletion policy before-hook-creation does not work when the pod in question is in some “running” state. For example plain Running but also ContainerCannotRun when the cluster blocks the execution for some reason like enforced nonRoot.

Whenever another helm test RELEASE is issued, the command fails with the message `Error: warning: Hook test […]/test-abborted-hook.yaml failed: object is being deleted: pods “rel-test-abort” already exists

Steps to reproduce:

1. add this test to any chart and install the chart.

apiVersion: v1
kind: Pod
metadata:
  name: "rel-test-abort"
  annotations:
    "helm.sh/hook": test-success
    "helm.sh/hook-delete-policy": hook-succeeded,before-hook-creation
spec:
  containers:
    - name: test
      image: "alpine"
      command: ['sh']
      args:
        - -c
        - "sleep 60s"
  restartPolicy: Never

1. run helm test [RELNAME] and hit CTRL+C before the test succeeded

2. run helm test [RELNAME] again and observe that it fails with “resource already exists”

Expected behaviour: Helm deletes the present resource before creating the new one as it is defined in the docs for the deletion policy before-hook-creation
