Issue

Customers get an error on checkout after the session timeout, even if the Persistent Shopping Cart is enabled.

Prerequisites:

1. Go to Config > General > Web > Default Cookie Settings > Cookie Lifetime and set to 120.
2. Go to Config > Customers > Customer Configuration > Online Customers Options and set both values to 2.
3. Go to Config > Customers > Persistent Shopping Cart and set to Enable.
4. Go to Config > Sales > Payment Methods and turn off all payment methods except Check/Money Order (it should be enabled).

Steps to reproduce:

1. Log in as a customer and add some products to the cart.
2. Check the shopping cart.
3. Wait for two minutes (set in precondition); the session should timeout.
4. Click Go to checkout and do not refresh the page.
5. Checkout as a guest, fill shipping address and choose a shipping method.
