core: fix crash in display of chat area when the ncurses chat window is not initialized

Browse Source 
This can happen when a window becomes too small for display: then we set the
ncurses chat window to NULL.
So when displaying buffer, we'll skip it if the ncurses chat window is NULL.

Steps to reproduce crash:
  1. /window splith
  2. /window resize -1 (many times, until chat area is less than one line)
  3. /window balance
