use unicode_state empty string before unicode_init. without define WITH_DOC_STRINGS.

PyType_Ready call PyUnicode_FromString, if doc string striped, cause crash.

unicode_get_empty() must not be called before _PyUnicode_Init() or after _PyUnicode_Fini()

PyType_Ready
```
const char *old_doc = _PyType_DocWithoutSignature(type->tp_name,type->tp_doc);
PyObject *doc = PyUnicode_FromString(old_doc);
```
