libs/python/src/exec.cpp: bug fixes

Browse Source 
Remark:
  operator!() for boost::python::object invokes PyObject_IsTrue()
  and is therefore not equivalent to "is None".
  In this particular case !global or !local returns true for an
  empty dict.
(Changes to libs/python/test/exec.cpp just helped in debugging.)
