Changed default user to be anonymous in both has_access and student.views.index
Corrected missing parenthesis and added test for has_access
Replaced existing test_none_user_index_access_with_startdate_fails
test with new test now that the tested function has changed and
was causing the original test to fail.
Pylint and PEP-8
