Jetpack: Subscriptions: confirmation emails use wrong url

[danjjohnson]

Steps to reproduce the issue

Subscribe to posts on a site with different urls for Site url and Home url

e.g. https://www.dfstudio.com

What I expected

The confirmation emails would include links to https://www.dfstudio.com

What happened instead

Both the 'Confirm your subscription' and 'Confirmed Subscription' emails contain links to the site url:
