[O] Bug: org-todo calls unbound org-clock-out-if-current

[Alex Branham]

Hello -

On the tip of the maint branch
(8fc22d464d2bc4a3397516854375b177835d10bb) any call to functions like
'org-todo' results in an error 'void-function org-clock-out-if-current'.

Here's a sample backtrace:

Debugger entered--Lisp error: (void-function org-clock-out-if-current)
  (org-clock-out-if-current)
  (org-todo "DONE")
  (funcall-interactively org-todo "DONE")
  (call-interactively org-todo)
  (org-agenda-todo "DONE")
  (my/org-agenda-mark-done nil)
  (funcall-interactively my/org-agenda-mark-done nil)
  (call-interactively my/org-agenda-mark-done nil nil)
