bug#24086: 25.1.50; ibuffer-do-view-1 fails to visit in new frame

[Tino Calancha <tino.calancha@gmail.com>]

When the argument TYPE is 'other-frame, it should visit
the buffer in a new frame.

emacs -Q --eval="(progn (require 'ibuffer) (setq ibuffer-expert t) (ibuffer))"
H
M-: (length (frame-list)) RET
=> 1
