Refactor datatrore handling in API requests

- Fully parameterized datastore(name)
- Improved controler testing to verify all parameter handling
- Simplified service inject (alwasy using contructors instead of @AutoWire)
- Added delay to fix isuse with intermitting failign test
  that tests invocation of a method that is executed on a separate thread
