python bindings: fixing decrypt-verify

* lang/python/src/core.py: First restoring the exception to the being
  just that.
* The means to manipulate the error output is temporarily in commented
  out code, but ought to be added to a proper test later.
* In the mean time the original test, with a very slight change, works
  again.
