loosen up hash_limit test

hash_limit_string works by doing a modulus of a hash value so that
the range of possible numbers is 0-N.  however, there's a chance
we might not populate every 0-N value in unusual cases on CI,
even after iterating 500 times apparently.  Loosen the change by making
sure we got at least N/2 unique hash messages but not greater
than N.
