* lisp/org-agenda.el: (org-agenda-get-scheduled) Don't call
  org-is-habit-p until after checking for for
  org-agenda-skip-scheduled-if-done.

Org-agenda-get-scheduled was calling org-is-habit-p on every scheduled
item (including DONE items when org-agenda-skip-scheduled-if-done was
set to t). Tweaking the timing of the test shaves some time off of
agenda construction when org-habit is loaded and
org-agenda-skip-scheduled-if-done is t.

Before:  org-is-habit-p  478         0.2434439999  0.0005092970
After:   org-is-habit-p	 81          0.057944      0.0007153580
