1.9.8: Empty folders remain after drag-n-drop

[moropus]

XnView: MP 1.9.8 64 bit
OS: Windows 10 64bit

Old folders in Folder panel in Browser remain in tree after drag-n-drop.

To reproduce:
1. Open Browser, open Folder panel
2. Select folder in the tree and drag-d-drop it to another folder
3. Notice that new folder appears in the tree

Actual behaviour (bug):
- Old folder from drag-n-drop source still persists in the tree
- I need to hit Refresh to make it disappear

Expected behaviour:
- Old folder hides instantly according to the drag-n-drop operation (move)
