Title: Fix critical irc_NICK bug

self.status returns the wrong mode, since you are using the new nickname instead of the old one. This corrupts the channel modes, and can result in erroneously giving privileges to users, in addition to demoting users on nick change.

And all of this happens silently because we don't broadcast the mode changes.
