Revert changes to add payment method button

[stitesExpensify]

Problem

In this issue we mislead a contributor to add some changes we don't actually. want.

Solution

1. We're getting the paypal.me nvp in getUserDetails now, we should get it exclusively in getPaymentMethods
2. We should never be hiding the "add payment method" button since we're going to be adding the ability for bank accounts to be added there and you can have as many as you want
