Handle if extension is already loaded when rendering multiple views

[beleneglorion]

When rendering multiple twig file in the same "controller" a LogicException is throw , you need to test if the extension il already loaded before add it

I had the same issue, using $app>share as in http://silex.sensiolabs.org/doc/providers/twig.html#customization solves it without calling $twig->hasExtension:

    if (isset($app['twig'])) {
        $app['twig'] = $app->share($app->extend('twig', function($twig, $app) {
            $twig->addExtension(new PagerfantaExtension($app));

            return $twig;
        }));
    }
