In Twig templates, the path( location ) function is not escaping special characters.

If legacy's urlalias_iri transformation mode is used, and content created with quotes, for example, it will break links generated through symfony / twig templates.

Steps to reproduce:

1. in ezpublish_legacy/settings/override/site.ini.append.php, add

   [URLTranslator]
   TransformationGroup=urlalias_iri
   

2. Create a content with special chars, such as Test " Article <>
3. Create or use template to view this content, for example:

   <a id="test" href="{{ path( location ) }}">
     {{ ez_render_field( content, 'title' ) }}
   </a>
   

4. Verify the link is broken.
