Fix some issues with shortcut containers opened inside folders.

- Dragging a shortcut from a container inside a folder was buggy
  because the folder assumes that all drags are removing an item
  (so it marks the cell as unoccupied, etc.). So we just close
  the folder when dragging a shortcut.
- When the shortcuts container opened outside of a folder, touches
  on it were incercepted by DragLayer to close the folder. So we
  move the container intercept check first, and return false if the
  touch is over the container so it can handle the touch.
