Update to determine sis enrollment sections

Changes for sections:

(1) SIS section id that matches the current course instance id, will appear first on the list

(2) Those sections with a sis section id which is also a course instance id will appear above those sections that either do not have a sis section id or does not have a course instance id
Does sections come sorted? I may not have caught the conclusion of the discussion, but last I heard the plan was to have all non-enrollment sections be alphabetical.
