Fix player formatters resetting too early on language change

formatters() is called again by the player before the user has a chance to click on the language in the language chooser.

So the correct solution would probably be to attach to https://developer.android.com/reference/android/content/Intent#ACTION_LOCALE_CHANGED, but let's keep it simple. I added `PlayerHelper.resetFormat();` in `ContentSettingsFragment.onDestroy()` and it works. It will mean the player formatters will be reset every time the user exits content settings, but whatever.
