馃崚 applets/folder: Don't use DesktopSchemeHelper::getFileUrl to get title
It isn't needed since we don't directly display it to the user; instead we poke and prod it in various ways and then return the processed string. This means we need the original URL, not a modified version of it, which makes KFilePlacesModel::closestItem() return the wrong thing.
KFilePlacesModel::closestItem() isn't doing anything technically incorrect here; it's our problem for giving it malformed data.
This fixes the Folder View widget having the wrong title when showing the contents of desktop:/, as it does by default.
