fix: add tearDown to clear event dispatcher after each test

- Add tearDown() method to ActiveRecordEdgeCasesTests to always clear event dispatcher
- Prevents state leakage when testEventsWithDispatcherThrowingException throws exception
- Ensures clean state for all subsequent tests
- Fixes 28 failing tests in GitHub Actions
