iCalendar routes are unusable

Current behavior

Both of the iCalendar routes are unusable:

• /conferences/…/schedule.ics raises NoMethodError: undefined method 'icalendar_proposals'.

• /calendar.ics redirects to / without explanation.

Expected correct behavior

Both endpoints should return iCalendar data.

Steps to reproduce

Minimal tests

Other information

#2717 added this feature without tests, so it’s not clear that it ever worked. #2977 apparently attempted a solution but didn’t address CanCanCan abilities.
