Title: HashRing iter_nodes is now able to visit all the nodes in the ring.

Before this commit the method was able to return all the nodes from the
first node up to the end of the array sorted_keys, representing the hash
ring.

However while the sorted_keys is an array, it represents a ring, so node
iteration should be able to traverse all the nodes in the ring, and
should always return @ring.size elements.
