Backport commit dd0727e1e from Emacs

* lisp/ol.el (org-store-link):
* lisp/org-clock.el (org-clock-sum)
(org-clock-update-time-maybe):
* lisp/org-colview.el (org-colview-construct-allowed-dates):
* lisp/org-macro.el (org-macro--vc-modified-time):
* lisp/org-macs.el (org-2ft, org-matcher-time):
* lisp/org-table.el (org-table-eval-formula):
* lisp/org.el (org-read-date, org-display-custom-time)
(org-time-string-to-time, org-timestamp-change):
Prefer (encode-time L) to (apply #'encode-time L) where either will do.
* lisp/org-clock.el (org-clocktable-steps):
Prefer (encode-time S M ...) to (apply #'encode-time (list S M ...)).
