Title: Fix a bug in kill-buffer-hook: can't kill the last

When there is only one buffer remains in the history list, this buffer
cannot be killed and the message like the following will be shown:

wlf:set-buffer: Buffer is null! at wlf:set-buffer. (left)

This change fix this problem.

履歴に残った最後のバッファが消せないバグの修正です。 #32 でこのバグを混入させてしまったみたいです。
