[PATCH] Fix for segfault on send message with silc plugin

[Skywing]

This fixes a segfault when using the silc-client-1.1.4 silc client plugin (i.e. 
loadable silc module for irssi and not replacing irc support with silc).  
Specifically, whenever you tried to send a message, we would segfault in 
skip_target() due to a null dereference.

Patch is against 0.8.12.
