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.


An `enrollment_count` parameter is set on the section in the `create_section` function prior to returning.  I could see a test that confirms that parameter was set on the mock section object.  An example of such an assertion using MagicMock is as follows: `sectionmock.__setitem__.assert_called_with('enrollment_count', 0)`
