Title: Fix issue trying to get previous_cards in admin payment view

Trying to get the previous_cards instance is broken:

`undefined local variable or method `previous_cards' for #<#:0x007fccce56e210>`

because in the view is trying to get `previous_card` method instead of `@previous_cards` variable
