[BUGFIX beta] Use @ember/ordered-set to avoid deprecations.

Ember will deprecate usage of `Ember.OrderedSet` (likely in 3.2 or
3.3), and as part of that process the implementation has been extracted
to an addon `@ember/ordered-set`. The addon intelligently avoids
shipping duplicated implementations, and is compatible with newer _and_
older Ember versions.

(cherry picked from commit d478a04)
