Issues:

Fixes #492

Problem:
Inheriting from the Resource class overrides the inheritence for the
load method in UnnamedResourceMixin

The result is that when using the ntp endpoint and loading the information,
an exception is raised.

Analysis:
The change corrects the order of inheritence

Tests:
na
