Fixed Incorrect Defer Flag During Theme Import

As described in https://documentation.coremedia.com/cmcc-11/artifacts/2201/webhelp/frontend-en/content/ThemeConfigReference.html you can set the "defer" flag in your theme configuration to defer the execution of a JavaScript file. Due to a bug all CMJavaScript documents generated by the theme importer that were not meant to be deferred were configured in a way that caused the following HTML output:

<script .... defer="false"></script>
