Regression after 0.13.0: no longer possible to identify an annotation with a newly created item

[jgonggrijp]

Today, a user reported that if she clicked "create new" when creating or editing an annotation, she could edit the new item, but the changes would not stick after clicking "save". I was able to reproduce this issue reliably both in production and in my local instance.

I have analysed the problem and I am currently working on a hotfix. The problem appears to be a logical mistake in AnnotationEditView. I find this somewhat surprising, because I don't think that code was changed in the 0.13.0 update. I'll report back here after fixing and further diagnosing the problem.
