Adds translation on the location views

[andrebonon]

Currently, the location views doesn't filter by the current language resulting on the views bringing duplicate results, for example a "Taggart Family Y" and its translation "Y de la famille Taggart".

Proposed solution:

• Views: Add a filter criteria "default_language", and filter by the default language in location views. It doesn't affect sites with only one language.
• Makes the Branch Labels (/admin/config/content/location-filter-settings) translatable via config_translation (module).
• Use the twig t() function so the "Filter by amenities" and the Search input placeholder can be translated
