bug#7231: 23.3; Don't rebuild buffer list in iswitchb-visit-buffer

[Leo]

The original change was to address buffer name changes due to packages
such as uniquify.el. But it causes another annoying bug: changing the
order of matches seen by users.

This reverts it.

If people are annoyed (which I doubt) by outdated buffer names due to
uniquify.el, one solution is to map the buffer-names to buffer objects
before killing and map them back to names after killing.

Subject: [PATCH] Don't rebuild buffer list in iswitchb-visit-buffer

Rebuilding buffer list will lose the order of matches seen by users
and thus cause surprises.
