test/trac-0193: correct test

The original solution fixed the exception when bindings were generated,
but the test passed only because of issue pabigot#78 which took four years more
to discover.  Revise the test to more accurately reflect what the
original fix enabled (and demonstrate the error in issue pabigot#78).
