Since witness terms are currently used as a way of specifying "replace t by skolem k, and send a lemma about k", a followup PR will update Theory::ppRewrite to take an additional argument std::vector<SkolemLemma>& lems where new lemmas must be explicitly added to a vector (instead of encoded as witness). Then, all Theory::ppRewrite will return skolems instead of witness terms.
