org-ctags.el: Fix an option default value back again.

* org-ctags.el (org-ctags-new-topic-template): Fix the option
default value back again.

This option was "fixed" in Emacs emacs-24 branch:
http://git.savannah.gnu.org/cgit/emacs.git/diff/lisp/org/org-protocol.el?h=emacs-24&id=0fc749f9

During an Emacs merge, I didn't check carefully and backported
this change into Org maint branch.  This is now fixed in Org and
in emacs-24.
