License breaks helm chart

[mortenbirkelund]

Describe the bug
After adding the license header in 3d2187d
the helm chart doesn work anymore, because the apiversion of the serviceaccount is being mistakenly seen as a comment.

Removing the license header, and then the chart works again. This only happens in the service account, because it is the only one that is deployed conditional depending on the values.

Steps to reproduce the behavior:

1. Go to the charts directory
2. run helm template .
