Fix 0.1.0 Helm chart to refer to correct container image version (#1349)

* Fix README to refer to current version of helm chart

 - Don't specify using :latest for the controller image
   in the README either as that defeats the purpose of
   hardcoding the specific image in the Helm chart.

* Fix 0.1.0 Helm chart to refer to correct container image version

 - Using :latest is not correct as that means it will always be
   pulling the latest version of the docker container.

* Fix possible null reference error
