Summary: Issue fixed: #414 - [x] All tests pass. Demo project builds and runs. - [ ] 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. - [x] I have reviewed the [contributing guide](https://github.com/Instagram/IGListKit/blob/master/.github/CONTRIBUTING.md) What should we do with testing? I changed all the occurrences of the old initializer with the new one, so I think this is good to go?
