Linking to an github project board and group by project status

[mehmet-kaya-1994]

In Github we can create projects with kanban board and move the issues in columns. In your extension github issue, we can make a query that links to the issues in the project ("query": "project:xxtestproject/31 sort:updated-desc",). Currenty this is working, but the grouping is not correctly. It always group it by repository and in each repository are the same issues. It would be nice to not group by repository or better if we can group by status like "todo, planning, in development, testing, finish
