Subject: remove superfluous deref

this is a very cute trick, but also one that's easy to cargo cult
incorrectly. only one deref is needed here (derefing from
Rc<Vec<Vec<u8>>> to Vec<Vec<u8>>) and then a reference can be taken
(&Vec<Vec<u8>>) which provides the desired into_iter. the second deref
goes from Vec<Vec<u8>> to &[Vec<u8>] which is unnecessary since Vec
already has an iterator over references.
