event log acts weird.

[fisx]

1. the initial data create doesn't trigger any, as it uses update directly instead of the higher-level actions.
2. the event log tests fail. (feed the example event log? see above
3. demo data triggers way too few event log entries. (race condition in writing to the file?)

(not confirmed.)

i will try to find the time to implement some load testing to confirm this is not an issue. we wanted to do that anyway.

Related #942. That change is just about avoiding mistakes in the future, so it doesn't fix any problems, especially not this here (if it exists).
