Testnet seed connects to Bitcoin cash node

[Varunram]

Something very weird happened when connecting to Peter Todd's testnet seed at testnet-seed.bitcoin.petertodd.org:

This issue might be a good chance to add a couple more testnet seeds from Core (even Peter's seed has changed URLs)

Connected to a BUCash node today, maybe should have a blacklist file..
