Item reordering returns an index of -100 if the item doesn't change order

[lbickston]

Short description of the problem:

If an item is minimally moved during a reorder such that it maintains its original ordering, indexes.to is set equal to -100 instead of the original index.

What behavior are you expecting?

indexes.to should be equal to the original index.
