Normally org-caldav-generate-ics export command reuse the ID from
property block to generate the *.ics, but it only works if the
SCHEDULED block is after the property block.
I don't know about org-caldav-generate-ics but
org-icalendar-export-to-ics works fine with the standard org format
(deadline & scheduled entries ahead of properties drawer). That
function is in ox-icalendar.el. Maybe try that instead of the
org-caldav-... method?
