Fix import of commonJS module with no default (#120)

PR #117 addressed an import of a common js module that assumed it had a
named export, which caused an error in some environments. It appears
that this fix broke other widgets with custom configuration as the
imported module does not have a default exported member.

This PR addresses both issues. It has been verified with the widgets
that broke before and after 10.18.1.
