Speed up WooCommerce’s “Get total spent” query

This is one of two ‘Power Tweaks’ which are a feature of WP-Optimize Premium.

When a customer places their first order, WooCommerce calculates the total spent by running a very slow query. This power tweak replaces this slow query with two separate and much more efficient queries.

This will be especially effective on e-commerce websites containing large amounts of customers and orders.

It uses the filterwoocommerce_customer_get_total_spent to calculate the total spent when the user meta _money_spent is not set.

This issue has been reported to WooCommerce, but not addressed yet (See issue on Github).
