Refactor landing page -> checkout e2e smoke tests

[tjmw]

What are you doing in this PR?

This is purely a refactoring to DRY up the new e2e tests which begin on the relevant landing page and navigate through to the checkout and complete a purchase. So far this has been done for the following smoke tests:

• Ad Lite
• Newspaper
• 3 tier products

Why are you doing this?

I noticed while working on these tests that the one piece which differed between them was transitioning from the landing page to the checkout. The rest of the work is common. The actual checkout form work continues to be done by completeGenericCheckout.

I've added a new function visitLandingPageAndCompleteCheckout which does the common work, taking a callback to handle the navigation from landing page to checkout.

How to test

Run the smoke tests.
