Fix test failures: update to new AddDependencyParams field names

- Update tests to use issue_id/depends_on_id instead of from_id/to_id
- Fix test_client_lazy_initialization to mock create_bd_client instead of BdClient
- Add workspace setup for lazy initialization test
- Fixes 2 test failures (now 123 passing, down from 121)
