Testing pod fails

### Expected behavior

Testing should just succeed

### Actual behavior

Testing fails

### Information

- Skaffold version: 2.7.0
- Operating system: Ubuntu 22.04
- Installed via: skaffold run
- Contents of skaffold.yaml:

```yaml
apiVersion: skaffold/v4beta6
kind: Config
metadata:
name: grafana
manifests:
helm:
releases:
- name: grafana
remoteChart: grafana
namespace: monitoring
version: 6.60.1
deploy:
kubectl:
defaultNamespace: monitoring
```

Grafana has a test pod. The pod succeeds but is then not marked as ready once successful.
Thus Skaffold prints:

> pods: pods not ready: [grafana-test]

### Steps to reproduce the behavior

1. `skaffold run`
