-Fix generic type error that occurs when using ChangeNotifier with a subclass of ChangeRecord.
-Previously, calling `notifyChanges()` on `class Foo with ChangeNotifier<CustomChangeRecord> {}`
-would throw a type error. Now, the `changes` stream emits a custom `ChangeRecords` class that
-implements the `List` interface. This change is backwards compatible.
