iCal files not generated for not public events

Overview

If an event is NOT public:

1. the Event Info page does not show a link to a calendar file.
2. If you go to the link to download the calendar file (drupal url ex: https://dmaster.demo.civicrm.org/civicrm/event/ical?reset=1&id={eventID}&list=1) the ical file is not properly populated.

Reproduction steps

1. Create an Event
2. Set "Public Event?" to unchecked
3. Go to the event info page for that event

Current behaviour

• No calendar icon to download the .ics file.
• if you go to the link that generates the ics file it is not properly populated

Expected behaviour

• The calendar icon to download the .ics file should appear as it does for public events.
• if you go to the link that generates the ics file it should populate as it does for public events

Environment information

Tested on master (5.29alpha1) in WordPress and Drupal

I suspect this is an oversight.
