    Settings: Remove dependency on pref object for min refresh rate isAvailable()

    Preference is not available during search indexing.

    Settings: Pass Locale.US when formatting refresh rate string

    * Some locales use comma rather than dot for floating point numbers
      thus causing NumberFormatException when trying to convert string
      to float.
    * Also make sure to strip `,00` too when needed.
