Display duties correctly for Cancelled orders

[rockeynebhwani]

Describe the current behavior
Dawn theme doesn't display duties correctly for a Cancelled order in My account and in Cancellation email. Changes to show duties were made as part of #1368 by @minh-tran-shopify but looks like this change didn't consider Cancelled order scenario.

This is how it looks in cancellation email. Totals don't sum up because duty component is missing -

This is how it looks in my account because we are using 'order.total_duties' and this is always 0 if order is cancelled.

Describe the expected behavior

Version information (Dawn, browsers and operating systems)

• Dawn Version: 5.0.0

Possible solution
Updated Cancellation Emails and my account order history display to show duty component so that order totals add up and make sense for the customer.

I can't find anything on order object which gives details of duty component when order is cancelled. This may required changes by Shopify first.
