Sortable: update event gets fired after calling cancel()

Affected browsers: any

Step-by-step:

• Open http://jsfiddle.net/1yu9Lpfm/1/
• Drag "Item 1" to a new position and hold it there.
• Wait for the timeout to call the "cancel"-event (after 2 seconds).

Expected behavior:

• The "update"-event should not be triggered, because the sorting was canceled and thus reverted.

Actual behavior:

• The "update"-event is triggered.
• Furthermore, the "update"-event is triggered before the "Item 1" is returned to its original position. If the application relies on the element's position in the DOM, it gets the false impression, that the element was in fact moved.
