Workaround DreddHooks::Server leftover by test suite
Workaround DreddHooks::Server leftover by test suite

The TCP Server feature starts a server but doesn't stop it.
This breaks the next test suite run unless the server is manually
killed, which is unpractical.

I think it's best to remove the entire feature until findinf a proper
fix to this issue and https://github.com/gonzalo-bulnes/dredd-hooks-ruby/commit/7330c74e6feb5799f616f1bf2d3fdf340bffb818
