fixed tests and fixed views

fixed tests for create_section, section_class_list, and section_user_list, also added new tests for resource_link_id, and fixed views.py where resource_link_id was missing from template render calls.


Along with the above comments, since the `resource_link_id` is required, I think it would be good to add another related test that just confirms that the `resource_link_id` was passed in correctly (i.e. matches  self.resource_link_id).
