Subject: [PATCH] Both ghost instances and exceptions to generated ghosts
 should be editable

Summary: Fixes T8369, Both ghost instances and exceptions to generated ghosts should be editable

Test Plan: Create recurring event, open /E{id}/1, edit, save. New exception should not be "recurring", and should be editable, as the regular ghost events.
