Fix crash in mainwindows_resize_smaller when the 'mainwindows' list is empty.
The crash can happen if the terminal height decreases before the first window is created. Based on a patch by Jaroslav Škarvada (red hat bug #796457). git-svn-id: file:///var/www/svn.irssi.org/SVN/irssi/trunk@5217 dbcabf3a-b0e7-0310-adc4-f8d773084564
