MultiDrag: onDeselect not works correctly

[jhonct12]

Hello again!!

I was testing the MultiDrag component, as a guide to the example of :https://github.com/SortableJS/react-sortablejs/blob/master/examples/components/multidrag.tsx

Everything works fine when it's one to one and select one per action.

It turns out that if two or more items are selected and then one of these is removed and given to any other item, the component stops working properly.

I reproduced the error and apparently it is in the event of onDeselect, evt.oldIndicies It does not contain the index, its value is undefined.

console generate error:

@jhonct12 Thanks for all that information, it really speeds up debugging

Fixed. Basically we should've used newIndicies and when newIndicies[x].index === -1, don't try to select it because it doesn't exist.
