[YouTube] Fix YoutubeChannelExtractorTest tests

- Change CarouselHeader test channel to Sports system one, as the Coachella one
doesn't return this channel header anymore;
- Fix InteractiveTabbedHeader test by checking whether the test's channel
description is not empty instead of containing some words, as it is changing
frequently.
