Passing a group to EntityAccessManager.isAdministrator triggers an XWiki permissions cache bug

Passing a group to PatientAccessHelper.isAdministrator (1.3) or EntityAccessManager.isAdministrator (1.4) results in a call to AuthorizationManager.hasAccess with a group reference. This may trigger XWIKI-12862 and cause loss of permissions for users belonging to that group if the group is not already in the cache.
