Improvements to License Expiration notification email

As part of our Marketing Automation, we send an email when a license is about to expire. To make it convenient for the user, we include special authorized links to quickly update or add a payment method if it was not there already. This comes in handy for partners who migrate customers from other platforms.

As an enhancement to the system, we’ve added a check to not include pricing for licenses that do not have any values set. This came as a request from one of our partners who recently migrated to Freemius.
