PDF export from wiki page menu not working if diagram page doesn't have attachment #84

When trying to export a diagram that doesn't have a file in the attachments section, the PDF exported from the wiki page menu does not include the diagram.

Tested on Chrome, Version 77.0, Windows 10 Pro

Current workaround was to add a modification to the diagram and then to save it in order to have an attachment appear in the dedicated section and to be able to see the diagram in a PDF export.

This actually happens on closed wikis only. On open wikis, when the image attachment is missing the export falls-back on the SVG export, which is not perfect, but the diagram should appear.

More details from the wider issue #29. On this comment #29 (comment) it is specified that the fix is working only with an extra editing (changes + save) step for diagrams created before 1.7

* Generate only the SVG image on save and store it as an attachment instead of using an object property
* Use the svg attachment for PDF export.

The diagram SVG has been moved from the diagram object to an attachment named diagram.svg which is always generated by the application (IE included). Existing diagrams are migrated when the Diagram Application is upgraded. If you delete the diagram.svg attachment by mistake then you need to edit and save the diagram page in order to regenerate it.
