NetworkImpl can't handle relayed addresses

If you try and dial an address that is relayed, e.g. /ip6/2a03:b0c0:3:d0::f5b:2001/tcp/4001/p2p/12D3KooWAYhKPvH8JrBT7oTiY69LY2QksfvPH2sY8ECvR1KD9ZTo/p2p-circuit/p2p/12D3KooWHci62Skj6sC6c2ASXARBnBMmUuM7kuHqtgi5mVQdJ6Gf

Then you get an error trying to set the peerid, because there are two p2p elements in relayed addresses. We want to append in the p2p-circuit case.

java.lang.IllegalArgumentException: Value (12D3KooWHci62Skj6sC6c2ASXARBnBMmUuM7kuHqtgi5mVQdJ6Gf) for P2P doesn't match existing value in /ip6/2a03:b0c0:3:d0::f5b:2001/tcp/4001/p2p/12D3KooWAYhKPvH8JrBT7oTiY69LY2QksfvPH2sY8ECvR1KD9ZTo/p2p-circuit

Start in NetworkImpl.connect at NetworkImpl.kt:72 and follow Multiaddr.withP2P through Multiaddr.kt:57-78. Reproduce the relayed-address dial using the address in the report, then verify that the existing relay peer ID is preserved and the destination peer ID is appended after p2p-circuit without the IllegalArgumentException.
