It's at least close to the “restore from disk” option. Maybe I 
should change the wording?

The “restore from disk” option deletes the database index files and 
then rebuilds them based on the emails in the disk cache. UIDs are 
stored as metadata with the emails and the paths to the emails provide 
the mailbox locations. When finished then the IMAP accounts are 
synchronized and this takes care of the rest (in particular any missing 
emails), but this is essentially the same as a regular sync cycle.
