bug#24873: 26.0.50; isearch-query-replace from regexp isearch doesn't add to replace-regexp history list

[Richard Copley <rcopley@gmail.com>]

Recipe from emacs -Q:

 M-<            ;; beginning-of-buffer
 C-M-s text     ;; isearch-forward-regexp
 M-% xxx RET !  ;; isearch-query-replace
 C-M-%          ;; query-replace-regexp
 M-p            ;; previous-history-element

Expected result: selects the previous replace operation "text -> xxx"
from the history list.

Actual result: signals "user-error: Beginning of history; no preceding
item".

The bug affects isearch-query replace when invoked during
isearch-forward-regexp but not when invoked during isearch-forward.

The bug was introduced in the master branch between these two revisions
(not tight bounds, just builds I have lying around):
