Changes proposed in this Pull Request:

Implements a dynamic check on whether to render the order details for a modal checkout cart.

The following should render the order details table:

• Cart has an applied coupon
• Taxes are enabled and set to display prices excluding taxes (feat: display purchase details in checkout modal when taxes are enabled #1480)
• Cart has more than one item

How to test the changes in this Pull Request:

1. Repeat steps from feat: display purchase details in checkout modal when taxes are enabled #1480
2. Disable tax rates and calculations on WC settings (or switch the "display prices" in the "tax" tab to "including taxes")
3. Enable coupons and create a coupon
4. Click on the checkout button and confirm the order details do not render
5. Apply the coupon and confirm the order details rendered with coupon details as the coupon is applied
6. Go through the entire checkout process and confirm the order is placed
