If a node is returning a peer list for a given blob hash
(being this been requested via CLI or via DHT) and it is
part of the resulting peer list, it will filter itself out
before returning the list.
This makes the results across the DHT inconsistent as
different nodes won't include themselves when
responding a findValue/findNode query.
Remove such filtering so that the local node ID is always
included when needed.
