KFileItemModelRolesUpdater: prevent generating twice previews for same indexes
KFileItemModelRolesUpdater::indexesToResolve until now could return a list containing multiple times the same index, resulting in previews being generated several times for those files.
This was noticeable when those files where directories since their previews are not cached and use a random number. Each time this would occur one could see the folder icon being updated shortly after the first icon had been loaded.
