audit_log: Update audit log entries created while creating a group.

Earlier a extra audit log entry of type
USER_GROUP_GROUP_BASED_SETTING_CHANGED was made when a new user
group is created. This commit updates the code to not create
that audit log entry.

There is no need to create these entry as we would still
have the required data from the "OLD_VALUE" field in the
audit log entry created when changing the setting and this
also makes it consistent with the entries created for
other operations like stream creation.
