Fixed normal bug EXT-3299 "Can't drag and drop landmarks into an empty favorites folder through landmarksSP"

- Added drag and drop for empty inventory panel. Dropped item gets to
the root folder.
- Fixed issue with empty "Landmarks" inventory panel not displaying "No
matching items..." message.
- Removed accordion updating and hiding in idle routine. This invalidates EXT-2346 "My Landmarks accordion panels shouldn't be displayed if there are no landmarks in respective folders"
