bug: fixing some installation related bugs (#30)

after introducing the token based authentication and the localhost
installation without ssh some bugs remained. these were caught while
developing the integration test suite for the project.

- the configuration overwrite question logic was inverted.
- we need to also create the namespace when installing custom helm.
- forcing the init script creation.
