Deactivate audit logger for group_created event in Studio

Due to the creation of computed groups at startup in Studio, the newly added (nuxeo-8.10-HF16) audit logging of the group_created event is trying to call Framework.getService in a separated thread during the server startup, which is not allowed by the Service passivator.

The quick fix is to deactivate the audit logging for this event.

A cleaner solution would be to avoid doing group creation before the server is fully started.

An even cleaner solution is to fix the bug in the platform (NXP-23520).
