The salvaged skip condition keyed on _use_draft_streaming alone, which
also suppressed the explicit REQUIRES_EDIT_FINALIZE pass when a
draft-streaming run had degraded to edit-based delivery (draft failure
fallback sets _message_id). Key the skip on the got_done update being a
fresh persistent send through the native-draft transport (_message_id is
None), which is the only case where the update already carried its own
finalize.
