(WebCore::MediaPlayerPrivateAVFoundationObjC::tracksChanged): Always call languageOfPrimaryAudioTrack(),
    a track may have changed so we may have a new language.
(WebCore::MediaPlayerPrivateAVFoundationObjC::languageOfPrimaryAudioTrack): Call [AVAssetTrack languageCode]
    if [AVAssetTrack extendedLanguageTag] returns NULL in case the media file has an old
    QuickTime language code.
