Jesse Squires a415ef5552 Prevent a crash when inserting the same index twice, re-open of #616
Summary:
Original comment:

If you insert or delete into the same index twice **and** update your data source to reflect those changes, we will squash the insert/delete into a single update because we're using `NSSet` internally.

This becomes very apparent when multiple updates are coalesced.

Issue fixed: #483

- [x] All tests pass. Demo project builds and runs.
- [x] I added tests, an experiment, or detailed why my change isn't tested.
- [x] I added an entry to the `CHANGELOG.md` for any breaking changes, enhancements, or bug fixes.
Closes https://github.com/Instagram/IGListKit/pull/634
