Fixes #7491 - moved default org and default location to same tab as org/...

...loc selection
It does that on the [client side](https://github.com/theforeman/foreman/pull/1774/files#diff-cff3cbacdf78b9d3385f298a838f4b4aR47). When loaded it show user's locations and changes on the client when selecting / unselecting a taxonomy.
