Predefined destinations in the restore page

Predefined destinations created under the "Destinations" page are convenient for setting up re-usable destinations. When creating a new backup, these destinations are shown under "destination". It would be convenient if the "Direct restore from backup files" would list these predefined destinations as well.

Start by comparing the restore page's destination control with the destination selector used when creating a new backup. Trace how predefined destinations are loaded and displayed in the backup flow, then make the restore page list the same destinations and verify that one can be selected for direct restore.
