kubectl-view-secret returns null for kubernetes.io/basic-auth secrets

When using `kubectl-view-secret` to retrieve secrets of type `kubernetes.io/basic-auth`, the output is null. This behavior differs from other secret types but I'm not sure. How to reproduce: ``` kubectl create secret generic my-secret --from-literal=username=admin --from-literal=password=supersecret --type=kubernetes.io/basic-auth secret/my-secret created kubectl view-secret my-secret password='' username='' ```
