Microsoft Graph Java SDK v.6.16.0 return empty site list with Username/password provider

[SashaUsov]

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.
