[Fixed 1.6.0]create_account_success doesn't honor session timeout

[lat9]

I realize that this is a "corner case", but for completeness ... if a customer
1) creates an account and gets distracted on the create_account_success page so that the session timeout kicks in
2) clicks the "Contact us" link
3) presses the "Back" button from the contact_us page

s/he is returned to the create_account_success page (because the page header doesn't remove the page from the navigation history) and is displayed the page with an empty "Primary Address" (because the session timeout has kicked in so there's no $_SESSION['customer_id']).

Here's an updated version of /includes/modules/pages/create_account_success/header_php.php that corrects these issues:
