Description of problem:
While create pvc using storage class, the pvc cannot be bound with dynamic provision

Version-Release number of selected component (if applicable):
oc v3.4.0.18+ada983f
kubernetes v1.4.0+776c994
features: Basic-Auth GSSAPI Kerberos SPNEGO

Server https://104.154.117.67:8443
openshift v3.4.0.18+ada983f
kubernetes v1.4.0+776c994


How reproducible:
Always

Steps to Reproduce:
1.Create storage two storage class via CLI as admin

$ cat default.yml | oc create -f -
apiVersion: storage.k8s.io/v1beta1
kind: StorageClass
metadata:
  name: default 
  annotations:
    storageclass.beta.kubernetes.io/is-default-class: "true"
provisioner: kubernetes.io/gce-pd

$ cat gcesc.yml | oc create -f -
apiVersion: storage.k8s.io/v1beta1
kind: StorageClass
metadata:
  name: gce
  annotations:
    storageclass.beta.kubernetes.io/is-default-class: "false"
provisioner: kubernetes.io/gce-pd

2. Create pvc on web console and select storageclass as gce
3. Check pvc status

Actual results:
PVC keeps pending status due to error below:

$ oc describe pvc wehe

$ oc get pvc wehe -o yaml
apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  annotations:
    volume.alpha.kubernetes.io/storage-class: gce
    volume.beta.kubernetes.io/storage-class: default
  creationTimestamp: 2016-11-02T02:36:28Z
  name: wehe
  namespace: wehe
  resourceVersion: "3255"
  selfLink: /api/v1/namespaces/wehe/persistentvolumeclaims/wehe
  uid: 283d1cc9-a0a5-11e6-a7c2-42010af00012
spec:
  accessModes:
  - ReadWriteOnce
  resources:
    requests:
      storage: 1Gi
  selector: {}
status:
  phase: Pending

There is a redundant of empty "selector: {}" to make this fail

Expected results:
PVC can be bound with dynamic provision
