Draggable Tests: Ensure scrolling and dragging tests assert correctly
Draggable: Clean spacing and names in connectToSortable drag callback
Draggable: No cloning in connectToSortable and ensure correct position

Draggables now forcefully recalculate their position when dragged out
of a sortable. Sortables now override draggable position when a
draggable is dragged into it. Lastly, no longer remove sortable helper
when dragging a draggable out, which allows us to not use a clone.
