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.
