[quantavi]

Steps to reproduce:

1. Sort by a column in list view
2. Click on any row to see its details
3. Go back to list by clicking appropriate breadcrumb or use following code in *_admin,rb file and pressing save to finish editing:

return_to do
    admin.path(:index)
end

Observed result:

1. User is redirected to list view, however the sorting is back to default

Expected result:

1. User is redirected to list view preserving sorting, that was previously selected
