Service list shows undefined:80 when type is ExternalName or LoadBalancer

Description of problem:
Service list has a Location column that shows the used ports of the service. But it shows undefined:80 (port from the resource) when the Service has type: ExternalName or type: LoadBalancer

Version-Release number of selected component (if applicable):
4.6-4.12

How reproducible:
Always

Steps to Reproduce:
Create a Service with type: ExternalName or type: LoadBalancer, for example:

apiVersion: v1
kind: Service
metadata:
  name: external-service
spec:
  ports:
    - protocol: TCP
      port: 8000
      targetPort: 8000
  selector:
    app: nodeinfo-d
  type: ExternalName
---
kind: Service
apiVersion: v1
metadata:
  name: loadbalancer-service
spec:
  clusterIP: 10.217.4.147
  ports:
    - protocol: TCP
      port: 8000
      targetPort: 8000
      nodePort: 31799
  type: LoadBalancer
  selector:
    app: nodeinfo-d

Open Administrator perspective > Networking > Services

Actual results:
Service list shows undefined:80 (port from the resource)

Expected results:
Service list should show just the port or more information for other Service types.

Additional info:
The Service details page uses a switch for .spec.type to show different information. See https://github.com/openshift/console/blob/7b741dd8898454cded10f6572fbebb1c4df1c8f9/frontend/public/components/service.jsx#L97-L125
