Running org-map-entries on an org file with tags results in an infinite
loop.

Example function using org-map-entries:

    (defun scrum-test ()
      (interactive)
      (org-map-entries '(lambda () (message "%s" (org-entry-properties
(point) 'standard))))
      (message "done"))

Example org file:

    * one
    * two
    * three
 :noexport:

expected result: visit each headline once then print "done"
actual result: visits headlines in an infinite loop and never prints "done"

It fails with: Org mode version 9.2.6 (9.2.6-elpa @
/home/ian/.emacs.d/elpa/org-9.2.6/)
It works with: Org-mode version 8.2.10 (release_8.2.10 @
/usr/share/emacs/24.5/lisp/org/)
It also works if the org file has no tags.
