Per T245790#6203701, we should exclude the article that a user just edited from the pool of articles to be suggested in the post-edit dialog. We should do this even if it's the only possible article, and instead show the "no suggestions" content.
Works as expected and the phab task T245790 was updated accordingly.
Moved for @MMiller_WMF review with a question - should we handle the following scenario?
- a user has only few articles returned in SE - say, only two
- a user makes an edit on the first one out of two articles and in the post-edit dialog sees the second article, clicks to edit it
- after saving an edit, the post-edit dialog will suggest to edit the first article again
