fix(issue1206): Need to use unsetZIndex=true in react-draggable-list

Fixes issue #1206
From the docs:
unsetZIndex is an optional property that defaults to false. If set to
true, then the z-index of all of the list items will be set to "auto"
when the list isn't animating. This may have a small performance cost
when the list starts and stops animating. Use this if you need to avoid
having the list item create a stacking context when it's not being
animated.
