Fixed used alias for "FOS\RestBundle\View\ViewHandlerInterface"

Changed `FOS\RestBundle\View\ViewHandlerInterface` to be an alias of "fos_rest.view_handler" instead of "fos_rest.view_handler.default". So in case if a custom ViewHandler has been configured under "fos_rest.service.view_handler" it will be used. Before this change, the used ViewHandler of Controller extending the `AbstractFOSRestController` would always have been pointing to `fos_rest.view_handler.default` because the service subscriber definition is `$subscribedServices['fos_rest.view_handler'] = ViewHandlerInterface::class;`.

This should fix #2029
