[YouTube] Fix stream tests failures

- Fix testCheckAudioStreams test of
YoutubeStreamExtractorDefaultTest.AudioTrackLanguage test class, by updating
the excepted audio track name test to use the updated English audio track name
(audio track type info has been added on the video tested);
- Fix YoutubeStreamExtractorDefaultTest.PublicBroadcasterTest test class by
using a different video from a French and German public broadcast channel, as
the channel Dinge Erklärt – Kurzgesagt is not affiliated with a public
broadcast channel anymore;
- Fix YoutubeStreamExtractorLivestreamTest test class, by updating the excepted
name of the livestream to the current one.
