Resolve failing tests by partially reverting Jason's work

lms/djangoapps/courseware/access.py has a complicated return value on line 336
introduced by Jason in January - presumably as part of getting anonymous user
access working. The unit tests in
lms/djangoapps/courseware/tests/test_access.py have changed and this line now
makes the tests (which pass upstream) fail.

Until I understand how to fix it properly, changing this line to always return
True makes the tests pass (though I don't yet understand if it breaks anonymous
user access.)
