[python-win32] Dispatches With Events on COM Object

It is that last step where things go wrong it seems.  If the object is
already a makepy wrapped object, we shouldn't call GetTypeInfo - the object
should just be used as-is.  We might need a similar check for a CLSID
attribute there (or better, a function eg, gencache.IsGeneratedObject() that
abstracts that implementation detail).  I'm afraid I'm out of time for today
though...
