pgpy.types.Exportable was renamed to Armorable before version 0.3.0 was released (in d00010ef04c0fe1353756b04cba257d2a75e5db9, back in 2014), which indicates that this test program has not been run in over 8 years.
Given that the asyncio stuff has also changed in python since then, it is simpler to just drop this file than try to fix it.
