Fix support for znc.in/playback module

self.lastMessageServerTime was being set to a date in future before the
*playback module was communicated the timestamp to start with. Now,
self.lastMessageServerTime is not modified until self.isLoggedIn has
been set to YES. This flag is sent after the *playback module has been
communicated with resulting in the correct value being supplied to it.
