Original room creator is still used for permission checks in some cases
Since !377 (merged) JWT claims are used to check for room roles. But in a few cases, logic still check for the original room creator instead. This hasn't been an issue until arsnova-http-gateway!109 (merged), because the rooms property was kept in sync with the room owner role.
This now causes issues when room ownership changes, e.g. when the user later updates a content or requests to delete its answers.
