Null pointer exception on passing empty search attribute in workflow options

[lazy-ninja]

Expected Behavior

It shouldn't throw a null pointer exception.

//return null for empty search attributes. 
SearchAttributesUtil.encodeTyped(options.getTypedSearchAttributes()); 

//on setting null search attributes in the StartWorkflowExecutionRequest, it will throw NPE
request.setSearchAttributes(startParameters.getSearchAttributes());

//StartWorkflowExecutionRequest#setSearchAttributes
if (searchAttributesBuilder_ == null) {
  if (value == null) {
    throw new NullPointerException();
  }

Actual Behavior

It throws null pointer exception

Steps to Reproduce the Problem

1. Create workflow options as

WorkflowOptions workflowOptions = WorkflowOptions.newBuilder()
      .setTaskQueue("queue")
      .setWorkflowId("workflow-id-1")
      .setTypedSearchAttributes(SearchAttributes.EMPTY)
      .build();

2. create workflow stub for any workflow

stub = workflowClient.newWorkflowStub(SampleWorkflow.class, workflowOptions);

3. Submit for execution

WorkflowClient.start(stub::execute, {});
