Fix 4763 so that additional properties work properly again

Fixes #4763 by removing the `name` from the `path` passed to `onChange()` for additional properties callbacks
- Updated `ObjectField` as described
- Updated `Form` to not pass `idPrefix` as the `name` to avoid it showing up as the title of the schema
- Updated `CHANGELOG.md` accordingly
