Panic after a music bot got stuck

[Jokler]

Describe the bug
If a music bot gets kicked the next poke makes it panic and as a result the master bot disconnects.
This should be the offending line since the master bot is still keeping track of the kicked bot:
https://github.com/Mavulp/pokebot/blob/3575ac579cdcc5a9fa3ffec84952a634d1d7deaf/src/bot/master.rs#L128

To Reproduce
Steps to reproduce the behavior:

1. Kick a music bot
2. Poke the master bot from the same channel the music bot was kicked from

Expected behavior
When kicked the bot should be removed from the list of connected bots but as with #26 this should not take down the master bot either way.
