Fixes #10091

Changes proposed in this Pull Request:

Currently, Jetpack does not output the GA tracking code in a specific case, which can be replicated as you see on #10091 :

• Enable Enhanced eCommerce option is active
• But WooCommerce is not active

Testing instructions:

1. Activate WooCommerce on a Premium or Pro site.
2. In https://wordpress.com/settings/traffic/my-site.com, activate Enable Enhanced eCommerce.
3. Deactivate WooCommerce
4. Visit the site without login as an admin.
5. Check the HTML output and find the GA code by searching Jetpack Google Analytics.

Proposed changelog entry for your changes:
