Add last pending step (including CC) to all textes en cours

[RouxRC]

Handle cases where texts are not published in the right order :

• for instance CC published but not final texte adopté

cf https://github.com/regardscitoyens/the-law-factory-parser/commit/dea0565f3406d5203863f35c179c021679ef5331

~I thought it was already the case, but it seems it is not always the case, for instance here: https://www.lafabriquedelaloi.fr/articles.html?loi=ppl17-337 with the TA AN hémicycle is awaiting publication http://www.assemblee-nationale.fr/15/ta/ta0164.asp pjl17-249~

Action plan to empirically test we always have the predicted step:

• [x] load all the "--in-discussion"' texts
• [x] check those have the right predicted step
  • [x] not working for https://www.lafabriquedelaloi.fr/articles.html?loi=15-ratification_accord_dialogue_politique_ue_cuba
    • [x] AN open data parser does not yet support yielding predicted steps https://github.com/regardscitoyens/anpy/commit/e19efb83bb452f409f1bf4fe6bd756d6ae3a7333
• [x] as there's no case with the CC as the current step, make sure it would works when there will be a CC step a087f51

Closed, for now :)

Seems like some cases are still not handled : https://www.lafabriquedelaloi.fr/articles.html?loi=15-ratification_accord_dialogue_politique_ue_cuba

Like for the dates, this should be tested properly in the backend : if we have neither an ongoing step nor an url_jo, we should report an issue

Now it raises an exception if this happens: 0c32f716fa2f557c983304c1471920be646a0691
