Subject: [PATCH 1/2] fix param ordering of gen_event crash

Currently we get error messages like the following logged:

```
2021-11-09T09:27:03.949055+00:00 error: Generic event handler ... crashed. Installed: .... Last event: {badarg,[{ets,match_object,[...],[{error_info,#{cause => id,module => erl_stdlib_errors}}]}|...]}. State: {event,...}. Reason: {state,...}.
```

This is very confusing (caused us to go on a rabbit hunt through our own
code for transposed `State`/`Reason` in `{stop,...}` return values).
