Increases zip code padding check to 4 characters for UK addresses #1151

What this does

Apple Pay anonymizes postal codes for British and Canadian addresses until the user has accepted payment. (source)

The mobile-buy-sdk accounts for this by adding padding to British and Canadian postal codes when Apple Pay only shows 3 characters. Some British postal codes have 4 characters, though, causing no padding to be added which causes errors in Apple Pay when attempting to get shipping costs.

An example postal code that causes this is WC2H 9BH in London. Apple pay will shorten this to WC2H.

This change increases the number of characters by 1 to allow these British postal codes to still apply padding.
