Fixing configuration according with changes done to router initializationThis change just moves router configuration to instance configuration of the router itself. The change is necessary to allow the router to be injected into other instances of the DiC and to eventually switch the router type to a custom one with own dependencies and eventually completely unaware of the default Zend\Mvc\Router\Http\TreeRouteStack. These changes are related to https://github.com/Ocramius/zf2/compare/zendframework%3A..mvc-router-from-locator
