Cart total doesn't update when using theme snippet switching language

Overview of the issue

When using a code snippet to display the cart total as suggested here http://docs.woothemes.com/document/show-cart-contents-total/, the total does not show up correctly when switching to a different language.
Steps to reproduce:

• – Two languages and two currencies: English (currency: GBP) and German (currency: EUR)
• – Use the first code (no AJAX) in http://docs.woothemes.com/document/show-cart-contents-total/ into the header. Call it “Custom header cart”.
• – Create a product both in English and in German: 10 GBP and 20 USD
• – Add the product in English to the cart.
• – “Custom header cart” displays correct the currency: 10 GBP
• – Switch to German
• – “Custom header cart” displays wrong: 10 USD
• – Refresh the current German page, “Custom header cart” displays correctly now: 20 USD

Workaround

A temporary solution user can add $woocommerce->cart->calculate_totals() after global $woocommerce and the actual snippet.

Will be fixed in the next version.
