No-op handler in READ_RESOURCE_DESCRIPTION handler

This handler addition isn't doing anything:

if (address.isMultiTarget()) {

.....

// Add a handler at the end of the chain to aggregate the result
context.addStep(new OperationStepHandler() {
@Override
public void execute(OperationContext context, ModelNode operation) throws OperationFailedException

{ context.completeStep(); }

}, OperationContext.Stage.VERIFY);
