Fix new tokens for moved sharing
Fix new tokens for moved sharing

When new tokens are generated to notify other instances that a sharing
has moved (the address of the Cozy has moved, and the sharing must be
updated to be exact), the client_id to use is the inbound_client_id (ie
the identifier of the client created by the other instance on the moved
instance), not the client_id of the client used by the moved instance.
