So that /spec/controllers/api/v1/
dossiers_controller_spec.rb#L163-L179 (on commit
8852431 for example) does not randomly fail due
to unordered types_de_piece_justificative
split procedure into 3 screen
desactivate order place for type de champ
desactivate features test to rewrite them
use ajax instead of pure js to manage type de champ
