Re-factor PDFViewerApplication._initializeAutoPrint slightly (PR 16779 follow-up)

Browse Source 
After the `src/core/`-changes in PR 16779 the `PDFDocumentProxy.getJSActions` method should no longer be able to return *empty* entries, which means that we can simplify the "JavaScript support is not enabled"-warning in the viewer.
Furthermore, improve the auto-printing hack used when scripting is disabled.
