Let eieio-persistent-read read what object-write has written

Browse source 
* lisp/emacs-lisp/eieio-base.el (eieio-persistent-validate/fix-slot-value):
  `object-write' may quote lists inside hash tables and vectors, so
  unquote those lists here.

This patch allows the eieio-persistent write/restore process to
perform a clean round trip. It only handles a very specific and
limited range of object structures, but at least the write and read
procedures match.
