That test seems entirely bogus given the new dispensation that we are
not going to error out on bad entries in listen_addresses. I'd counsel
just getting rid of it.

What does it mean to specify "18.104.22.168 22.214.171.124 126.96.36.199"?
If we want to prevent people from writing redundant listen_addresses
lists, we'll have to work a lot harder than this. But I don't see the
point of trying.
