Permissions removal propogated to children with unique permissions but not in delta

2 issues:

• When a user is remove from a folder, it propagates to children with unique permissions
• The permission changes on the children are not reflected in the delta query when calling a deltaLink got from previous run.

Minimal rerpo for permission not being available in delta url:

• Create a folder and a file within it
• Add/Remove permission from child file to make it have unique permission
• Add a user to the parent folder
• Call /delta and get delta.nextLink
• Remove permission from parent folder
• Call link got from delta.nextLink (you'll see the child file is not present even though the permissions for it was changed)

The delta url is called with Prefer: deltashowremovedasdeleted,deltatraversepermissiongaps,deltashowsharingchanges,hierarchicalsharing header as suggested in the docs both the times. The problem only happen on the first the user is deleted and work on subsequent deletions.
