Fix org-clock-load

Since commit fda64f1ae2 on November 6,
org-clock-load no longer restores clocks in org-clock-persist-file. The
contents of the file look like this:

(setq org-clock-stored-history '(("/home/matt/org/inbox.org" . 39479) ("/home/matt/org/reading.org" . 63478)))

The files both exist; the position information is correct; and
org-clock-persist is t. And yet after calling org-clock-load,
org-clock-history, org-clock-loaded, and org-clock-stored-history remain
nil.

The problem, it seems, is that the logic/order of the if statement was
reversed in the commit above. The attached patch should fix the issue.

Best,
Matt
