You can use the export back to mailbox options - this will not results in duplicates (you won't have the shortcut and archived item) - unless the user has moved archived items from the original folder where they were archived , which is likely.
With your webapp restore method...once you have restored the items to the user's mailbox - you can do an advanced find in outlook, select the mailbox root and subfolders and search on message class ipm.note.enterprisevault.shortcut - this will bring back all shortcuts and you can delete them in one go.
Hope this helps
