Steps to reproduce:

1. Enable staging for blogs.
2. Add a blog entry with an inline image (drag and drop in the content).
3. Publish to live.

Expected: Each entry has a different URL for the inline image and 2 file entries can be found in the db.
Actual: The URL is exactly the same which means that it has been ignored during the export and there is only one image in the database (the one from staging).
