Wrong code in get_defined_custom_field_type and get_defined_custom_field_types

1. get_defined_custom_field_type:

        self._uri, work_item_type_id, key
        should be :
        self.project_id, work_item_type_id, key)
   

2. get_defined_custom_field_types:

        self._uri, work_item_type_id
        should be:
        self.project_id, work_item_type_id
