You have a very big problem here:

class ModelManager extends ModelManager

You try to extend class from self. It's wrong! You need to declare your base class with Fully Qualified Name or use use statement. Also you forgot to put namespace declaration. Something like this will work:

namespace Acme\Bundle\DemoBundle\Model;

use Sonata\DoctrineORMAdminBundle\Model\ModelManager as BaseClass;

class ModelManager extends BaseClass
