print resource kind prefix when `kubectl get all` has single type to display

**Release note**:
```release-note
NONE
```

This patch forces the HumanReadablePrinter to display resource kind
prefixes when there is only one type of resource to show and a specific
resource type has not been specified as an argument to kubectl get

`$ kubectl get all`
```
NAME         CLUSTER-IP   EXTERNAL-IP   PORT(S)                 AGE
kubernetes   172.30.0.1   <none>        443/TCP,53/UDP,53/TCP   2m
```

`$ kubectl get all`
```
NAME         CLUSTER-IP   EXTERNAL-IP   PORT(S)                 AGE
svc/kubernetes   172.30.0.1   <none>        443/TCP,53/UDP,53/TCP   2m
```
