YamlConfigurationSource wrongly resolves exported YAML app config, reference to log.txt for an example.
Steps to reproduce:
1. import destination app from XML file config.modules.tours.apps.destinations.xml to modules > tours > apps
2. test it as it's working correctly
3. export 'that' configuration into YAML
4. remove JCR configuration, rename exported YAML file to destinations.yaml and put it to lightdev module under apps folder
5. open the app and see the issue
Work around:
1. remove first line app name ('destinations' in this case)
2. convert all 'extends' property to use our YAML 'inherit' mechanism
Expected result:
Work seamlessly w/o any modification or provide correct message to end user to fix the configuration.
Suggestion:
Upgrade YamlConfigurationSource.
