[Bug Report] Bot stays in voice channel when playback fails

[RasmusAntons]

Describe the bug When playing a song fails because no search query is provided or no results are found, the bot stays in the voice channel without playing music, even with StayInChannel set to false.

To Reproduce Steps to reproduce the behavior:

1. Execute !play without a search query or something like !play uylicuytb while in a voice channel and the bot not playing music already.

Expected behavior Either the bot does not enter the voice channel at all or it disconnects immediately after the error message is sent.

While this isn't necessarily intentional behavior, this and any other problems related to staying in a channel for too long can already be resolved by setting the alonetimeuntilstop value in the config file
