Spree::Core::ControllerHelpers::PaymentParameters#move_payment_source_into_payments_attributes

This method handles the awkwardness of how the html forms are currently
set up for frontend.

This method expects a params hash in the format of:

 {
   payment_source: {
     # The keys here are spree_payment_method.id's
     '1' => {...source attributes for payment method 1...},
     '2' => {...source attributes for payment method 2...},
   },
   order: {
     # Note that only a single entry is expected/handled in this array
     payments_attributes: [
       {
         payment_method_id: '1',
       },
     ],
     ...other params...
   },
   ...other params...
 }

And this method modifies the params into the format of:

 {
   order: {
     payments_attributes: [
       {
         payment_method_id: '1',
         source_attributes: {...source attributes for payment method 1...}
       },
     ],
     ...other params...
   },
   ...other params...
 }
