node: relax converge criteria

Some test flakes would occur due to the `converge` function looping
forever. It was noticed that in these cases the log output would look
like:

    test: Node z6MkqTKLVnFdVF24PQiDoQffbTPT7U5igghS3XWuFJLfah1P has
    {(Id(rad:z39WuDs9hrqmCr9shjoz6dn2Abqyz),
    PublicKey(z6MkemMxfWhRQFKy4UPX7FsN8GjLAZ9T65rbmDsUn7fchioP)),
    (Id(rad:z39WuDs9hrqmCr9shjoz6dn2Abqyz),
    PublicKey(z6MkpdPJp7naAurUjCpwef1BDD5jfPhAvwfinaGd7pVh227j)),
    (Id(rad:z39WuDs9hrqmCr9shjoz6dn2Abqyz),
    PublicKey(z6MkqTKLVnFdVF24PQiDoQffbTPT7U5igghS3XWuFJLfah1P))}

with further investigation, the variable `all_routes` was found to be
smaller than the calculated routes.

Instead of checking `==`, instead check that
`routes.is_superset(&all_routes)`, which means that `routes` must be
equal to `all_routes`, but allows it have extra entries.
