ACL list have a PHP error when there are ACL on objects

Description

In some cases people can affect ACL to a single object, either by activating the ACL tab on all objects or by using the ACL creation dialog on the object DN. In this case we get a PHP error when showing the list because the object has no ou field, and we get an empty line so it’s hard to know which object it is.
