Move integration test (DataService)

- Moved all Data Intergation Test
- Added/improved some module Moudle Servcie test too
- Removed some unused (impossible) code-paths in prod code
- Replaced null's with meaningful strings (in edge case scenarios)
- Replaced @Shared with static (shorter) in some test
