Error when selecting channel from commends

[theScrabi]

So I encountered the first bug in commends support. Some chnnels you can select from the commends end up in having a stacktrace. Somehow these channels use a different URL format. This case should be handled in order not to make the app crash.

I suggest to transform the url. So if you get a url like https://youtube.com/calligraphymasters add a usrer/ in the middle so it looks like this https://youtube.com/user/calligraphymasters.

@yausername please fix this before we can release the next version.

Exception

• User Action: requested channel
• Request: https://youtube.com/calligraphymasters

[yausername]

transforming the url does not work always.
for https://www.youtube.com/jpltoyexperience neither https://www.youtube.com/user/jpltoyexperience nor this https://www.youtube.com/channel/jpltoyexperience exist
but luckily we have a way to fetch the channel id https://www.youtube.com/channel/UCQTOFh22Pl3p81Z4KlufVCg
PR is open TeamNewPipe/NewPipeExtractor#141
Thanks
