Clear existing IRC event handlers before connecting to new ones (irc) (#2138)

Browse Source 
Clear IRC event handlers that we will be registering for the new
connection before registering new handlers. This prevents duplicate
event handlers in the case where we are connecting via a BNC and are
seeing a reconnect. Attempting to clear handlers when none have been set
is a no-op.

Fixes 42wim#1564
