[FIX] mail: Escape translated emoji strings

Steps:
- Install knowledge on a fresh db
- Install and set fr_BE language
- Open knowldge
- Traceback

The traceback occurs because `emoji_registry.js` fails to load `emoji_data.js`
because of some translated string that contains non-escaped characters for JSON
