org-agenda.el: Fix bug about 'time-up sorting strategy not being honored

* org-agenda.el (org-search-view, org-agenda-get-todos)
(org-agenda-get-timestamps, org-agenda-get-blocks): Use the
dotime parameter of `org-agenda-format-item' so that 'time-up
and 'time-down agenda sorting strategies are handled correctly.

Thanks to Richard Lawrence who reported this.
