Added Spec Tests for 2 Operations

Added to spec tests to very that the operations...

For testing batch delete node :
 - 2 node created one by one
 - Nodes deleted in batch
 - Get nodes results should be nil

For testing batch remove node :
 - Create two nodes with indicies one by one
 - In batch remove the node from the indidicies
 - Search for exact nodes should be nil
