Use hash style for AR queries

[roman-dubrovsky]

Prefer a hash style that string style for AR queries

#bad
workflow_scope.where("id = ?", params[:id])

# good
workflow_scope.where(id: params[:id])

I think this rule should be included to the rails rubocop config so we don't need to add a separate rule

I've spent some time in order to find this cop, but I haven't found anything. Looks like we have to implement our own
