appt.el fixes for bug#7019.

* lisp/calendar/appt.el (appt-check): If not displaying the diary,
use (diary 1) to only get the entries we need.
(appt-make-list): Sort diary-list-entries, if we cannot guarantee
that it is in day order.  (Bug#7019)

        * calendar/appt.el (appt-check): Rather than showing the diary,
        just turn off invisible display, and only if needed.
