FolderView and AllView currently check if the item is present in the BaseAppView._items map, in order to avoid adding the same icon multiple times. Now that BaseAppView._loadApps() has a different role -- it returns a list with all app icons, and BaseAppView diffs with the current list of app icons -- checking the BaseAppView._items map is wrong. Make sure there are no duplicated items in the temporary array returned by all _loadApps() implementations. Remove the now unused BaseAppView.hasItem() method. https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/645
