Cannot unarchive channel as bot user

[aidandj]

Ran into some issues getting this running. If I use a bot token it cannot unarchive channels because of this bug

But if I use a user token I get an error that i cannot add or remove self from channel.

I was thinking about either adding support for both user and bot tokens, or maybe checking if user is self before adding/removing, but wanted to see if there was another workaround.
