Handle missing versions of non modified accords

[RouxRC]

• Dépot initial manquant :
  • pjl08-036
  • pjl08-037
• Texte de la commission manquant :
  • pjl12-508
• Texte adopté intermédiaire manquant :
  • pjl16-173

(misplaced in anpy before regardscitoyens/anpy#13)

[mdamien]

Two solutions:

• manually fix them with a hardcoded list (like for Handle rectifications texts by the Senate / AN #33)
• if there's no amendments, display the same text as before (especially if we detect it's an "accord")

Manual handling could also fix issue with pjl13-502 listed in #84
