fix: event entrypoint incorrectly pointed to request type registry

* There was a copypaste mistake in ext - event type entrypoints
  were loaded into the request type registry
* The fix replaces it with the correct registry and adds tests
  that demonstrate that correct registries are filled by
  entrypoints
