Description of the issue

This relates to the readme file at https://github.com/Azure-Samples/active-directory-aspnetcore-webapp-openidconnect-v2/blob/master/4-WebApp-your-API/4-1-MyOrg/README.md but it may apply to other readme files in this repo as well (I did not check in all of them)

In this section below to add from MyAPIs, the API created earlier with the other app registration will not show up because it has no owner.

So please update the documentation for the earlier section for TodoListService-aspnetcore-webapi to add a step to set the Owner of the application.
