b/15428113 p/72247322 Made findAuditors return a deferred that resolves to a list;
There is also an optional flag added to operate in the classical style, because if_auditor would need to defer_render, and if_helpers currently can't work with helpers that defer (we have if_auditor in if_helpers in several places).
