Fix create method on model doctrine events

[shyim]

Doctrine Events are missunderstood as Hook and the Hook template was generated.

This PR fixes the generated code for Doctrine Events (Shopware\Models\Article\Article:postRemove)

Following template is now generated

<?php
public function foo(\Enlight_Event_EventArgs $args)
    {
        /** @var \Shopware\Models\Article\Article $entity */
        $entity = $args->get('entity');
    }
