dossiers: save draft by default (instead of submitting)

Make the default behavior of `update_brouillon` be to update the draft,
instead of submitting the dossier.

This makes all requests made to `update_brouillon` without specifying
an extra `submit_draft` parameter to just save the draft. It will make
autosaving the draft easier and safer.
