Enable and update lobby-server controller integration tests (#9572)

- Re-enable most of the tests by fixing database data setup.
- Simplify tests by removing some of the test scaffolding
- Update tests to be more like acceptance tests rather than
  just integration tests. Acceptance tests, or contract tests,
  verify a work flow, while integration tests just verify
  if there is connectivity and if requests can be sent.
