Resolves #4490


This fixes an issue where namespaces in dynamic chunks were not referencing reexports correctly because imports were missing. See #4490 for the issue.

The problem was that the logic to make reexported variables available was run before facades were generated, and facade generation could add additional namespaces to the module.
