az network private-dns zone list fails with wrong error message

### Describe the bug

When calling `az network private-dns zone list --subscription ` with a subscription which exists but does not contain a private dns zone, I get any error message indicating the subscription does not exist.
This is incorrect, the error message should instead indicate that no dns zones was found in the given subscription.

You could also argue that no error message should be displayed, but instead an empty list should be returned as the result.

### Related command
