Management of Child Class References

[cedricfrancoys]

For objects referencing a class in an object_class field (such as log, translation, task, mail, ...), support must be added for child classes in case of inheritance or override (since the same table is used).

To retrieve certain meta objects (log, task, ...), the search is performed based on the entity name (with namespace) of the child class. However, in some cases, it might be the name of the parent class that has been registered in object_class.

For that reason all searches should be based on the root parent class name.
