## Description
All calendars except the default are nested under a "Other Calendars" folder. Having a non-default calendar named the same as the default calendar does not cause problems when fetching the default calendar by name. Only the default calendar will be returned in that situation.
This fixes the bug where we had multiple collections for the same path but representing different folders.
Also updates the restore execution path to handle the new nested folder structure.
Backup, incremental backup, and restore flows tested manually
