Nice catch! Thanks @derDuffy

It's not a big deal to fix it, but I'll @To-om decide when he can fix it :)

It is not easy to fix this issue because logs haven't owner, they only have creator (user who did the action).
When a case is merged, logs are created in the new case and the creator is the user who initiate the merge action.

To fix this issue, I can add a new attribute "owner" to log entity but a schema update is required. I can also hack entity creation process to overwrite creator value.

This can't be done for TheHive 2.13

@nadouani in front-end, use attribute "owner" instead of "createdBy" (or "user") to show the owner of the log. This will solve this issue.
