Drive: remote move to a folder registered as a sync root for another user is not handled as a local deletion

This case was detected in a specific use case (take a deep breath) : the remote move of a child (C) of a folder (F) shared with and synchronized by userB to the personal workspace of userA (parent of F) sync root for userA is not impacted client side (should be deleted).

To reproduce it step by step:

• As userA register userA's personal workspace as a sync root
• As userA create folder F in userA's personal workspace
• As userA grant "Manage Everything" to userB on F
• As userA create folder C in F
• As userB register F as a sync root
• As userB bind Nuxeo Drive to this Nuxeo instance => should have F with C as a child in the Nuxeo Drive folder (OK)
• As userA move C to userA's personal workspace => should delete C from F in the local Nuxeo Drive folder, this is KO
