Add bonus sibling check for PageGroupDescription
All children pages of a bonus PageGroup are bonus
No need for bonus and isLastOfSequence fields in PageGroup

Bonus is set in PageGroupDescription.Position, and in children pages of
pageGroup, but not pageGroup itself. That information is lost at the

level.
