bug#19436: 24.4; dired-insert-subdir with saveplace

[Tak Kunihiro]

On `dired-insert-subdir' with saveplace on, point goes to random place.

0. emacs -Q
1. (require 'saveplace)
2. (setq-default save-place t)
3. M-x dired
4. M-x dired-insert-subdir
5. I expect point goes to top of the new inserted directory.
   However, it goes to random place.
6. It seems that it has something to do with dired-initial-position-hook
   in dired-initial-position.
