kitemlistview: cancel editing when animation starts

For this widget.

If a file is being moved due due to external events, an animation may
start, in which case we better cancel the edit.

If we hook this at the animation start instead of checks spread out, we
can't miss this cancellation anymore.

KStandardItemListWidget gets a cancelRoleEditing slot to cleanly cancel
editing and clean up its internal state.
