LGTM with only small remarks.
We may think of how to compare resultset unordered.
Also now this change is in contradict with my PR.. but that can be solved as soon as this one gets merged.

We may think of how to compare resultset unordered.

Yes! I changed the case to check for the number of content topics subscribed and not their values to avoid complexity, as I think the check is strong enough in this case.

The problem here why I didn't use a set is that there's two layers of order: there's the list of peers, and within each peer there's a list of content topics. So we would have to use a set of sets, or something like that, and might overcomplicate things.

There might be a more elegant solution, we can think it through :). Sorting is also a option but kind of tedious in this case, for the same reason.

Also now this change is in contradict with my PR.. but that can be solved as soon as this one gets merged.

Yes! Once this is merged we'll probably have to rebase your PR to include this fix :))
