Wrong card number validations

The first case is when passing an empty string, the resulting object asserts true. It was supposed to return false, right?

import pagarme from 'pagarme'
...
console.log(pagarme.validate({card: {card_number: ""}})))

Another cases are bad errors handling for miscellaneous inputs:

This works and returns true, as it should be: console.log(pagarme.validate({ card: { card_number: "4242424242424242" } }))

But sending the same input as integer: console.log(pagarme.validate({ card: { card_number: 4242424242424242 } }))

Also, this returns true either: console.log(pagarme.validate({ card: { card_number: "424242424242____" } }))

It took me a while to actually realize what wrong with my code, as the documentation here says nothing about this validate method, and the documentation at https://docs.pagar.me/docs/obtendo-os-dados-do-cartao is too simple.

@MarcoWorms Taking advantage of the issue.

When i try to create a card_hash sending just the number 1 in the card_number, the following exception was launched:

But when i send other number, like 4, the following ocorred:

With it, i guess the problem is with the BIN validations, cause the number 1 does not belong to anyone brand, and the number 4 belongs to Visa.

(Não sabe como sofri pra escrever tudo isso em inglês, e provavelmente em um inglês deplorável xD)

The problem with the validation is because of this:

https://github.com/pagarme/pagarme-js/blob/master/lib/validations/validate/card/cardNumber.js#L41

const reduFinalSum = withoutLastDigit => (acc, digit, index, digits) => {

According to the documentation, the order should be

const reduFinalSum = withoutLastDigit => (digit, acc, index, digits) => {

Notice the order of the digits and acc arguments.
