Python code generated with '-builtin -modernargs' segfaults for any method taking zero arguments.

Also fixes: "SystemError: error return without exception set" during error checking
when using just -builtin and the incorrect number of arguments is passed to a class
method expecting zero arguments.

Closes #256
Closes #382
