Description

This MR fixes #2404 by avoiding trying to set a type field to the config if such config was not available as object because there is only a single URL to point at when a PyWorker is bootstrapped.

This basically invalidated the assumption it was Polyscript fault being unable to understand configs, it was actually our stdlib initialization.

Changes

• avoided type assignment for an otherwise empty config within the worker which defaults to the used string out of the DOM declaration
• added a test that verifies everything works as expected

Checklist

• I have checked make build works locally.
• I have created / updated documentation for this change (if applicable).
