Annotation:

Some users reported some bugs that the bot did not left the voice channel after entering -m stop or after finishing the track queue.
The user KBU#3846 reported the following error trace:

But on my testing I could not reconstruate the bugs, so I have no chance to fix this bug in this version. I have chaged some things in the music class in hope that this will probably fix this error. If you clould clone the repository and try to fixt this bug by yourself if it's occures on your guild, so I would really appreciate if you could make a pull request with your fix.

Thanks!
