PublicClientApplicationBuilder.CreateWithApplicationOptions does not respect the audience

[jmprieur]

Which Version of MSAL are you using ?
MSAL 3.0.0-preview

Platform
Any (for instance desktop)

What authentication flow has the issue?
Any (this is app config)

Other? - please describe;

Repro

PublicClientApplicationOptions options = new PublicClientApplicationOptions();
options.AzureCloudInstance = AzureCloudInstance.AzurePublic;
options.AadAuthorityAudience = AadAuthorityAudience.AzureAdMultipleOrgs;
options.ClientId = "ebe2ab4d-12b3-4446-8480-5c3828d04c50";

var app = PublicClientApplicationBuilder.CreateWithApplicationOptions(options)
                                                 .Build();
string authority = app.Authority;

Expected behavior
authority should be https://login.microsoftonline.com/organizations/

Actual behavior
whereas it is https://login.microsoftonline.com/common/

Note that
If we override the options with
.WithAuthority(options.AzureCloudInstance, AadAuthorityAudience.AzureAdMultipleOrgs), this works correctly ...

Important
When this bug is fixed, please remove the work around in the following samples:
