test: use the regular libp2p host (#565)
Browse files Browse the repository at this point in the history 
This removes dependencies on swarm/testing and the blank host.

1. swarm/testing really shouldn't be used at all except for internal
libp2p stuff.
2. The blank host should only be used in _very_ special cases (autonat,
mostly).
