Add tests for chained reexports from a hybrid module (#7980)

* Add test for chained reexports from a hybrid module

This captures a case where a CJS export is missing.

* Add test for reexports as default from a hybrid module

This captures a case where packaging fails
with `Asset was skipped or not found`.

* Use strict equality checks

* nit: match similar test terminology
