tdf#165917 Improve Export directory pre-selection

When calling an Export dialog (PDF, epub, ...) the following
folder will be preselected:

For stored documents:
* Current document directory
* If another directory was chosen for the export,
that directory will be preselected for subsequent exports
(stored only during runtime - per document)

For unstored documents:
* The last used export directory is restored (last used in unsaved doc)
