nyl template should error if only one namespace defined in a file and other resources are not in that namespace

[NiklasRosenstein]

Example:

---
apiVersion: v1
kind: Namespace
metadata:
  name: foo

---
apiVersion: inline.nyl.io/v1
kind: HelmChart
release:
  name: redis
  namespace: sccache
chart:
  # Explore the chart at https://artifacthub.io/packages/helm/bitnami/redis
  repository: https://charts.bitnami.com/bitnami
  name: redis
  version: "20.0.3"
values:
  architecture: standalone
  master:
    persistence:
      enabled: true
      storageClass: hcloud-volumes
      size: 64Gi

This should have nyl template error that resources are in the sccache namespace despite only foo being defined. What you actually get is
