Steps to reproduce

1.  Edit tour content type and change description property name to description_in
   • https://demoauthor.magnolia-cms.com/.magnolia/admincentral#app:resources;/tours/contentTypes/tour.yaml::
2.  Go to Tours content app and add a new tour inside of the magnolia-travels folder (make sure to fill in description_in property)
3. See that this property is missing from the delivery endpoint data 
   • https://demoauthor.magnolia-cms.com/.rest/delivery/tours/v1

Expected results

description_in property should be present in the delivery endpoint data

Actual results

Workaround

Do not use "_in" to end property names (even "_ins" works)
