Allow guest access without password to courses searched

Configure 2 courses with guest access: one with password and the other without. Access the app using a user not enrolled in any of those courses. Search the course with password, go to the details and check that you can't access the course. Now search the course without password, go to the details and check that you can access the course (but not participants, grades, etc.). Do the same with a course without guest enabled and user not enrolled. Check that you can't access the course. Enable self enrolment in the course without password. In the app, go the the details (where you can see the "Contents" button). Self enrol yourself in the course and check that now you can see the rest of addons (participants, grades, ...).
