[FIX] website_sale: abandoned cart wrong template

To reproduce the issue:
1. Go to Settings > Website
2. Activate "Automatically send abandoned checkout emails"
3. Click on "Customize Abandoned Email Template"
4. Template "Gamification" appears

Error: The template "Ecommerce: Cart Recovery" should have
appeared instead

The hardcoded res_id was wrong
