tdf#123476 filter: Also handle empty ODF

This builds on top of commit ada07f303e7cd1e39c73abe0741aefe7d9d73a57,
to allow 0-byte ODT, ODS etc.

Possible TODO would be somehow use default template for such empty files,
getting the template name using SfxObjectFactory::GetStandardTemplate.
That would enable using 0-byte ODF files as means to "create new document
at this location from default template" workflow.
