Fix test logic for up-to-date file detection in locales_to_js_spec.rb

- Set JS file modification times to be newer than YAML files
- This ensures files are truly considered 'up-to-date' by the obsolete? method
- Fixes test failures where files were being updated when they shouldn't be
- Both translations.js and default.js files now have consistent timestamps
