[FIX] website_sale: toggle shipping state display

In 1ef52c9c the code displaying state of a given country was improved
for some incompatibilities.

But, if when setting the billing informations we choose to create a new
shipping address, the shipping state* would not be displayed even when it
should be (currently, if the shipping country is Australia or U.S.).
