Silent PayPal failure

[micahalcorn]

From a user:

We are testing the shopping cart and the checkout experience on the commerce site we are building on D-Shop. There are issues after checkout when on the PayPal page where after entering all info into Paypal it just reverts back to the data entry page.

Issue, as seen in my development environment:

Paypal.payment.failure.mov

Additional information:
This issue affects users whose stores use custom themes; I have not been able to reproduce it on a store using the 'Default' theme.
One point of failure is in the rendering of the PaymentChooser component, once the browser returns from interacting with Paypal:

dshop/shop/src/components/payment/Chooser.js

Lines 15 to 19 in f65491f

	const PaymentChooser = ({ state, setState }) => {
	const { config } = useConfig()
	const [{ cart }] = useStateValue()
	const paymentMethods = get(config, 'paymentMethods', [])

The state variable passed as a "prop" toPaymentChooser should include the shop's configuration details. Only then will the config variable be set correctly. The re-rendering of PayWithPayPal may then continue.
