Plugin keeps the same value for every contact in campaign batch

Hi,

It looks the twig expression result value from the email template for the first contact in campaign is repeated for every contact in a campaign.

To reproduce:

1. Create email template with Twig expression extracting data from contact/lead filed
2. Prepare campaign sending email from template above and make sure your campaign is build for segment >1 contacts
