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.


I think the two following tests should be restructured a bit.  For both tests, the call to `check_resource_link_id` should be mocked out.  One test would be to verify that the function was called with the expected parameters.  In a second test, the return_value of that mock would be set to False and you'd verify that context_error was made.
