        This method converts the course id string to a CourseLocator object
        and returns the filtered queryset. This is required because
        CourseEnrollment course_id fields are of type CourseKeyField

        Query parameters with plus signs '+' in the string are automatically
        replaced with spaces, so we need to put the '+' back in for CourseKey
        to be able to create a course key object from the string
