Fix relation undefined error.
This error was caused by the scenario of having multiple ICQ clients
(non-EMchat) connected. If one or more of the other clients cycled its
connection it could cause the HELLO CID to be sent to EMchat, which would
get rather confused seeing as though it wasn't in the middle of logging
in.
To work around this we just force a disconnect. If the user has saved
their password EMchat will then attempt an auto-reconnect. After the new
connection is established all is good again.
* emchat-v8.el (emchat-v8-fetch-flap): Disconnect when a bogus
FLAP header comes in.
