Problem: The test value for the expiration date was being shown on gift card reports that don't have expiration dates.
Purpose: The expiration date should only be shown if it's set for the gift card code.
It will be consistent with loyalty_report and the email template mail_template_gift_card in which both conditionally displays the expiration date.
Steps to Reproduce on Runbot:
1. Install Sales
2. Settings > Sales > Enable Discounts & loyalty programs
3. Navigate to Sales > Gift cards and create/generate a gift card code with no expiration date
4. Print the gift card report and the report will show the expiration date of 2023-12-31
