Prevent multiple listings of organization when creating a repository (#11303)

prevent double entries in results of GetOrgsCanCreateRepoByUserID

I first try to only add GroupBy directly but xorm return broken user objects ...

... solution was to just query related UserIDs(OrgIDs) first and return OrgUsers based on this IDs
