[Core] - Class entity - OU name is set to be unique but this is not mandatory

Changes of ou=unique $this->attributesAccess\['ou'\]->setUnique('one')
It is not mandatory to have a unique name for the OU, only the refID.

The line will be removed, allowing to put an already existing name to a new OU.
