fix(MenuLinkUrl): Handle translation of URls

[joaogarin]

This PR is somewhat related to #809 which adds multilingual support for menu links. That works well, however in our case we are passing the language parameter to the menu, and that seems to not get carried away to the URL.

The label is translated fine but the URL itself (which in our case is not translated in the menu item its just the original URL) is not really picked up..the link is to a node so it should be possible to return the translated URL

Our resolvers look like this :

Getting the menu :

// Menu query.
$registry->addFieldResolver('Query', 'menu',
  $builder->produce('menu_load', [
    'id' => $builder->fromArgument('name'),
    'access' => $builder->fromValue(FALSE),
    'language' => $builder->fromArgument('language'),
  ])
);

getting the menu items :

// Menu items.
$registry->addFieldResolver('Menu', 'items',
  $builder->produce('menu_links', [
    'menu' => $builder->fromParent(),
  ])
);

Item URL :

// Menu url.
$registry->addFieldResolver('MenuItem', 'url',
  $builder->produce('menu_link_url', [
    'link' => $builder->produce('menu_tree_link', [
      'element' => $builder->fromParent(),
    ]),
  ])
);
