Use Braintree instead of Stripe on Laravel 5.3

Hello,

I use this : https://laravel.com/docs/5.3/billing (Braintree) but when I test payment, the system search the stripe_id column in database.

How to force use Braintree instead of Stripe ?

SQLSTATE[42S22]: Column not found: 1054 Unknown column 'stripe_id' in 'field list' (SQL: update `users` set `updated_at` = 2017-05-18 23:01:28, `stripe_id` = cus_*** where `id` = 1)
