[Bug]: Command logging doesn't work without a bot icon

[Dominiola]

Bug description

If the Discord bot you're running Lavamusic with doesn't have an app icon, then the command logging doesn't work, throwing an exception each time.

The commands are being logged properly only after setting an app icon in the Discord Developer Portal.

Steps to reproduce

1. Set no app icon for your Discord bot
2. Set LOG_COMMANDS_ID="<some channel id>"
3. Start Lavamusic
4. Commands will not be logged and Lavamusic logs show errors
