Fold CLOCK and LOGBOOK drawers upon creating them

* lisp/org-clock.el (org-clock-find-position): Use a faster call to hide
  clock drawer.
* lisp/org.el (org-log-beginning): Make sure logbook drawer is folded as
  soon as inserted.
(org-store-log-note): Remove unnecessary call to
`org-cycle-hide-drawers'.
