"what's new" crashes on channels that do not have a videos tab

[ghost]

Here is an example for such a channel (I've found by a chance..):
https://www.youtube.com/channel/UCAjUDZ-2r1B0ig88Ak56Scw

I've subscribed to it (before finding out about the bug), and every update to the subscription list ("what's new") you'll get an error (I think NewPipe still updates the list from other channels but I'm not sure).

Exception

• User Action: requested feed

As you can see on youtube, the channel has no video tab. We only support video tab for now, therefore we display this message (before this, it used to produce an error everytime you browse the channel).

See #3201, it's planned to have playlists tab in 0.20 version for youtube, and more for SoundCloud / PeerTube.

Well, no. "this content is not supported" is literal, having no public videos is just a side effect. The content is not yet supported, since the channel can not be parsed. It will be after @wb9688 pr with channel tabs will be merged.
