[BUG] conflict feed queries with count aggregation return empty results

[tvaron3]

Describe the bug
conflict feed queries with count aggregation return empty results. Serialization of query node is failing because expecting storeResponse with resourceKey Document instead of Conflict.

To Reproduce
Steps to reproduce the behavior:
Create some conflicts in a container. Try a count query on a conflict feed.

Code Snippet

CosmosAsyncClient client = new CosmosClientBuilder().endpoint(serviceEndpoint).key(key).buildAsyncClient();
CosmosAsyncDatabase db = client.getDatabase("db1");
CosmosAsyncContainer cont = db.getContainer("container");
CosmosQueryRequestOptions options = new CosmosQueryRequestOptions();
options.setPartitionKey(new PartitionKey(0));


CosmosPagedFlux<CosmosConflictProperties> conflictCountQuery = cont.queryConflicts("select value count(1) from c");

List<FeedResponse<CosmosConflictProperties>> conflictCountQueryResults = conflictCountQuery.byPage().collectList().block();
for (FeedResponse<CosmosConflictProperties> conflictCountQueryResult: conflictCountQueryResults) {
      System.out.println("Number of count conflicts: " + conflictCountQueryResult.getResults().size());
       System.out.println("Cosmos Diagnostics: " + conflictCountQueryResult.getCosmosDiagnostics());
