Title: Don't use .next() to get next AsChainLink in AS chain for redirect 

It's unnecessary and can hit and assert if at end of chain. It's unnecessary because in a redirect case we only need to know about the original chain so we know to switch to a new target and start terminating services again - exactly where we are in the chain doesn't matter.
