P2P PeerBook newPeers and tiredPeers lists should be disjoint

[valamidev]

Expected behavior

• Peers in the PeerBook newPeers / tiredPeers never exist in both list.

Actual behavior

• When baseList.removePeer() fail it could occur that Peers are remain in the list.

Steps to reproduce

• With the code sample below it can be reproduced.

if (!peerBook.hasPeer(peerInfo)) {
					peerBook.addPeer(peerInfo);
	}

	peerBook.upgradePeer(peerInfo);
});
