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.
