* Fixed uninitialized pointers in "__init__" methods of UnaryFunction1D types.

There was a known issue for a long time that we occasionally encountered
strange "TypeError: an integer is required" and "RuntimeWarning: tp_compare
didn't return -1 or -2 for exception", as shown in the following unit test
log.  The source of the former error was PyInt_AsLong(obj) being used by
IntegrationType_from_BPy_IntegrationType(obj), where "obj" was not properly
initialized in "__init__" before the converter was called.  The TypeError
was left unattended for a while and showed up when a comparison occurred
and the TypeError was detected, which resulted in the latter warning.

* Also removed unnecessary error messages in "__init__" methods of
UnaryFunction1D types.
