Issue GoogleContainerTools#836: Use releaseName to get release info.

The helm release name can be templated so within the `deployRelease`
function the `releaseName` variable should be used any time the release
name is desired.

This commit updates the final call to `getDeployResults` to properly use
the `releaseName` variable.
