query-replace-regexp undo: Update next-replacement after undo
* lisp/replace.el (perform-replace):
Use last-replacement for the local binding to not shadow next-replacement.
Update next-replacement after undo (Bug#37287).
* test/lisp/replace-tests.el (query-replace-undo-bug37287): Add test.
(query-replace-undo-bug37073): Tweak this test.
