Restore removal of old addresses

[nazar-pc]

I was supposed to restore it before merging #2242.
Restored version has filtering condition flipped (that was a bug in the old version that had to be corrected).

Code contributor checklist:

• I have read, understood and followed contributing guide

This PR is actually problematic and will be fixed once we upgrade to libp2p/rust-libp2p#4596
Here is an example:

Old addresses: ["/dns/bootstrap-0.gemini-3g.subspace.network/udp/30533/quic-v1", "/dns/bootstrap-0.gemini-3g.subspace.network/tcp/30533", "/dns/bootstrap-0.gemini-3g.subspace.network/udp/30533/quic-v1/p2p/12D3KooWQkJUqsc27Vx8Hvc9nSQzv2DezPxFKtozNKz61mVrB7f8"]
Identify addresses: ["/ip4/52.207.215.137/tcp/30533", "/ip4/52.207.215.137/udp/30533/quic-v1", "/ip4/172.19.0.2/tcp/30533", "/ip4/127.0.0.1/udp/30533/quic-v1", "/ip4/127.0.0.1/tcp/30533", "/ip4/172.19.0.2/udp/30533/quic-v1"]
Old addresses: ["/dns/bootstrap-1.gemini-3g.subspace.network/udp/30533/quic-v1", "/dns/bootstrap-1.gemini-3g.subspace.network/tcp/30533", "/dns/bootstrap-1.gemini-3g.subspace.network/udp/30533/quic-v1/p2p/12D3KooWPTtJXa8Pfx9NfTxQdLoatVGyidybfg5t3ASmD1F1aMzF"]
Identify addresses: ["/ip4/44.202.126.148/tcp/30533", "/ip4/172.18.0.2/udp/30533/quic-v1", "/ip4/44.202.126.148/udp/30533/quic-v1", "/ip4/127.0.0.1/udp/30533/quic-v1", "/ip4/172.18.0.2/tcp/30533", "/ip4/127.0.0.1/tcp/30533"]

Example above is a complete mess, identify doesn't return external addresses for some reason, some of the Kademlia addresses are with and some without /p2p/ID.

requires libp2p upgrade

Checking strings is not the most efficient solution, but it is the most compact and shouldn't be a huge bottleneck

multiformats/rust-multiaddr#105 once resolved will help to avoid dealing with strings
