Microsoft Graph Java SDK v.6.16.0 return empty site list with "*" and ""(empty) search query parameter

Describe the bug

Create GraphServiceClient with UsernamePasswordCredential provider

var provider = new UsernamePasswordCredentialBuilder()
                .clientId("client_id")
                .username("username")
                .password("password");
var graphClient = new GraphServiceClient(provider);

Call graphClient.sites().get().getValue()

Expected result: receive a list of the sites
Actual result: an empty list was returned without any error.

GraphServiceClient with ClientSecretCredential provider works as expected on graphClient.sites().get().getValue() call.

SDK Version

6.16.0

首先使用 UsernamePasswordCredentialBuilder 通过 GraphServiceClient.sites().get().getValue() 重现该问题，然后将其与 ClientSecretCredential 进行比较。调查 SDK 在每个凭据提供程序下如何处理空的或 "*" 的站点搜索查询。当 username/password 流程返回预期的站点列表，且未导致 client-secret 流程回归时，即表示完成。
