secondary index: update test.py
secondary index: update test.py

I forgot that I also need to update test.py for the new test.

It's unfortunate that this script doesn't pick up the list of
tests automatically (perhaps with a black-list of tests we don't
want to run). I wonder if there are additional tests we are
forgetting to run.
