bug#12647: 24.2.50; emacs --daemon broken in tty

[Toby Cubitt <tsc25@cantab.net>]

"emacsclient -c" throws an error if "emacs --daemon" is started outside
of X windows, . This is on a recent bzr checkout (from today).

Steps to reproduce:

1. switch to a linux virtual tty

2. emacs -Q --daemon

3. switch to X windows

4. emacsclient -c aborts with the following error:

   Waiting for Emacs...
   *ERROR*: Wrong type argument: stringp, nil


(This bug breaks the Gentoo emacs daemon init scripts.)

Note that "emacsclient -nw" does still open tty frames successfully on a
daemon started from a tty. And running "emacs --daemon" from within X
windows allows emacsclient to create both types of frame successfully.
