updatePending method Null safety
Updates the OwnershipModel.path of pending OwnershipModel.
Queries the NodeService for each OwnershipModel.transactionId and check if it was commited to update the OwnershipModel.path. It uses the FIFO order to update the OwnershipModel and stops in the first one that was not updated yet, since the transactions are updated in FIFO order too.
Implementation
void updatePending() {
throw UnimplementedError();
}
