Moved unused autocall tests into a doctest that does get run now.

+"""These kinds of tests are less than ideal, but at least they run.
+
+This was an old test that was being run interactively in the top-level tests/
+directory, which we are removing.  For now putting this here ensures at least
+we do run the test, though ultimately this functionality should all be tested
+with better-isolated tests that don't rely on the global instance in iptest.
