Memory leak when PyErr_SetObject is used

[pyscripter]

The pattern

PyErr_SetObject(PyExc_TypeError^, PyUnicodeFromString(
          Format(rs_ErrInvalidArgs,
          ['CreateComponent', rs_InvalidClass])));

is used in WrapDelphi and elsewhere. The problem with that is that the created Unicode python object is not released and over time this increases memory consumption.
