Script hides coupon button

[fzemmel]

Describe the bug
In adyen-payment-method.phtml "btn-primary" is used as selector for the place order button.
If you have multiple buttons with this class, they are hidden too.
In my case it hides the "apply coupon" button when I select PayPal for payment.

To Reproduce
Steps to reproduce the behavior:

1. Go to '...'
2. Click on '....'
3. Scroll down to '....'
4. See error

Expected behavior
It would be better to use "btn-place-order" as selector for the button.
Hiding all buttons on the page seems a bit too much.
