first news after migration dicarded silently

[lukasz-virtualo]

After installing the plugin (including migrations) and then adding a first news item (via admin interface) results in the form being accepted but no news items appear on the list.
Second time around everything works.
Tested on both local development server and staging serwer, same issue.

The more puzzling thing is that there is in fact a record in the News model with a set date in the field published. However, it neither shows up in the admin nor via manager (News.published.all()).
