Failing test: manually adding nodes with no bootstrap

[gmaclennan]

As far as I understand the docs, it should be possible to create a swarm by creating each node without any bootstrap nodes, and then manually adding each node to the routing table. However, this fails with the error:

Error: Too few nodes responded

This is a failing test for that issue.

Everything from here onwards is unchanged from the previous test (above)
