"kubectl get cells" shows cells from past incarnations of Controller

[myechuri]

Setup: minikube on MacBook with VK shipping pods to GCE.

kubectl get pods does not show any nginx pods, but kubectl get cells shows nginx-deployment-66f967f649-9b8zj.

Cell for nginx-deployment-66f967f649-9b8zj is listed with instance id i-0ec6eabbae4ca4c6b which corresponds to a cell running on AWS from a previous incarnation of vk which shipped pods to AWS.

Verified that the current setup is indeed shipping pods to GCE and not AWS:
