An ArrayIndexOutOfBoundsException is thrown in headless api if you sort using a non-localizable DDM field

Steps to reproduce

1. Create a webcontent structure
2. Add a field in that structure and in the advanced setion, set:
   • "field reference" to 'myField' value
   • "localizable" to disabled
3. Get the ID of the created structure
4. Go to the command line and execute:

   curl "http://localhost:8080/o/headless-delivery/v1.0/content-structures/[STRUCTURE_ID]/structured-contents?sort=contentFields%2FmyField" -u '[USER_EMAIL]:[USER_PASSWORD]'

   Replace [STRUCTURE_ID] with the ID of the created structure. Replace the [USER_EMAIL] and [USER_PASSWORD] with the user email and password

5. Check the log file and the returned data:
   • Expected behavior: No error is produced and an empty array is returned
   • Wrong behavior: An INTERNAL_SERVER_ERROR - Index 3 out of bounds for length 3 error is returned, if you check the log file, an ArrayIndexOutOfBoundsException is thrown in the log file
