Busty doesn't seem to change her name back to the original string after a bust

[anoadragon453]

#8 added a feature where the bot would change their name to that of the currently playing song. When all songs had finished playing, or an admin calls !stop, the bot should change it's name back to what it was called originally.

While that did seem to work in testing that PR at the time, the functionality seems to have broken along the way. The bot's name does not change after the final song finishes playing, nor when an admin calls !stop, leaving the bot's name as that of the last played song.

This turned out to be caused by this line:

busty/main.py

Line 156 in ae00e92

original_bot_nickname = bot_member.nick

bot_member.nick will be None if the bot does not has a guild-specific nickname set. If original_bot_nickname was None, operations such as:

busty/main.py

Lines 110 to 113 in ae00e92

	# Restore the bot's original nick (if it exists)
	if original_bot_nickname and current_channel:
	bot_member = current_channel.guild.get_member(client.user.id)
	await bot_member.edit(nick=original_bot_nickname)

would not fire.

Ensuring original_bot_nickname is set correctly will avoid this error. This is fixed in #21.
