I think this is too strict: given that I am providing the name of the context to use, there is really no point in requiring a "current" context.

@ankon thanks for reporting, I think this is a bug in the used Kubernetes client library. I wanted to switch away anyway, see #112 (haven't checked yet whether this would fix this issue).
