Fix: `org-agenda-skip-scheduled-if-deadline-is-shown': show TODOs without deadline
* lisp/org-agenda.el (org-agenda-get-scheduled): If
`org-agenda-skip-scheduled-if-deadline-is-shown' is set to
'repeated-after-deadline, still show tasks without any deadline
The problem was that the check for the deadline seems to return a
default time even if no deadline is set for the task. This adds a
check if there is a deadline at all, if there is none, the task is
shown in the agenda, otherwise the old semantics apply.
