Issuing NICK during session breaks JOIN

[toolness]

When I issue a NICK command and later issue a JOIN command, the following exception is thrown:

node_modules/irc/lib/irc.js:549
                    throw err;
                          ^
TypeError: Cannot read property 'users' of undefined
    at Client.<anonymous> (/Users/atul/Documents/explorations/irc-fun/node_modules/irc/lib/irc.js:325:28)
    at Client.emit (events.js:88:20)
    at /Users/atul/Documents/explorations/irc-fun/node_modules/irc/lib/irc.js:546:22
    at Array.forEach (native)
    at Socket.<anonymous> (/Users/atul/Documents/explorations/irc-fun/node_modules/irc/lib/irc.js:543:15)
    at Socket.emit (events.js:67:17)
    at TCP.onread (net.js:362:31)

It looks like that's right here. The exception is being thrown because self.nick wasn't updated when the NICK command was issued.

Found this error too, the problem is indeed in that line
