Filter UUID paths not working

The autoexport:filteruuidpaths property configuration for the auto export module doesn't work as expected. Adding another path still results in the uuids being exported.

Reproduction

1. Create 12.0.2 archetype project
2. Add news feature through Essentials, recompile and restart
3. Add "/content" to /hippo:configuration/hippo:modules/autoexport/hippo:moduleconfig/autoexport:filteruuidpaths
4. Recompile and restart
5. Create a new news document in the cms, save

Expected

The new news document auto-exported yaml doesn't contain jcr:uuid properties

Observed

The new news document auto-exported yaml does contain jcr:uuid properties
