Regression - New document has already translations after first creation

Reproduction path:

• log in on https://cms.demo.onehippo.com as editor
• use the "Create a news document" link on the dashboard
• add the required title and save the document.
• click on the language button in the document actions

It appears that there are already translated documents available. Clicking on the links without the green plus sign brings you to documents in other channels, but that is clearly wrong.

I guess something is wrong with the hippostd:translationid's that are set. Or is it a problem with the document wizard plugin?
