AutoDevops doesn't create SSL/TLS secret and ingress controller logs errors

A customer is having issues with setting a GKE cluster from autodevops and getting the following errors when using ingress.

AutoDevops says everything has installed correctly but my `ingress-nginx-ingress-controller` is filling stackdriver with the error:

> error obtaining PEM from secret dashboard-8230855/production-auto-deploy-tls: error retrieving secret dashboard-8230855/production-auto-deploy-tls: secret dashboard-8230855/production-auto-deploy-tls was not found
