fix --save-config in create subcommand

--save-config option doesn't work.
```
#kubectl create rolebinding a --role=b --user=c --save-config  
rolebinding "a" created
```
old output:
```
#kubectl get rolebinding a -o yaml
apiVersion: rbac.authorization.k8s.io/v1beta1
kind: RoleBinding
metadata:
  creationTimestamp: 2017-01-23T10:09:48Z
  name: a
  namespace: default
  resourceVersion: "281"
  selfLink: /apis/rbac.authorization.k8s.io/v1beta1/namespaces/default/rolebindings/a

roleRef:
  apiGroup: rbac.authorization.k8s.io
  kind: Role
  name: b
subjects:

expected output:
