Further fix to eieio-persistent

* lisp/emacs-lisp/eieio-base.el (eieio-persistent-validate/fix-slot-value):
  Make handling of hash tables and vectors recursive. This is
  necessary because the write process, in `eieio-override-prin1' is
  also recursive. With any luck, this will be the last fix of its
  kind. If that's true, cherry-pick to Emacs 26.2 later on.
