fix: remove refresh token on access denied

[Nicklason]

When logging in the bot removes error listeners and only adds them back when successfully logged in. This means that if you first start the bot and get the accessdenied error, then the bot will keep crashing because it keeps trying to sign in using the invalid refresh token.

Bot registers handler for error events on the client:

Bot removes error listeners when attempting to log in:

Bot does not handle access denied errors in the login error handler:
