Cannot have empty whitelist AND blacklist

[rafaeldamasceno]

📝 Description

If you try to have empty whitelist AND blacklist at the same time to allow all sources, the bot fills the whitelist with youtube.com, effectively only allowing YouTube as a source.

🪜 Reproduction Steps

1. Run /managesources and leave both lists empty.
2. Run /play with a non YouTube source
3. The "source not allowed" message is printed

ℹ Environment / Computer Info

• Parrot version: 1.5.0
• Operating System: Official Docker image

There's an undocumented trick for this. Add "." As an entry to the blacklist.

[rafaeldamasceno]

Yeah, I do this. Anything goes for the blacklist entry and the whitelist stays empty, but it's not immediate nor intuitive 😄

@rafaeldamasceno Thank you for the report. Yes, this is sort of an oversight on #223. You can get around it (as you and @StaticRocket both said) but I'm still not entirely happy on how intuitive this command is. Do you (or anyone) have a proposal for a better implementation?
