MSA-18-0015: Web service core_course_get_categories may return invisible categories

by Michael Hawkins.  

It was possible for the core_course_get_categories web service to return hidden categories, which should be omitted when fetching course categories. Note this only affects cases where a user has access to manage categories, but does not also have permission to view hidden categories.
