[BUGFIX release] Ensure nested custom elements render properly.

A bug was introduced with the Glimmer update that was included in
Ember 2.13 that caused an error to be thrown when using nested
custom elements like:

```hbs
<foo-bar>
  <baz-qux></baz-qux>
</foo-bar>
```

The fix was done upstream in glimmerjs/glimmer-vm#488.

(cherry picked from commit 15c2d25)
