Can not extend android.content.ContentProvider

Reproduce el fallo con la demo vinculada de nativescript-content-provider y su AndroidManifest.xml, comenzando por la extensión ContentProvider y el stack trace de Runtime.initInstance. Compara el comportamiento de NativeScript con el ejemplo funcional de Android puro del informante; se considera terminado cuando la aplicación se inicia sin fallar y se llama a la consulta del ContentProvider para obtener el directorio.

Environment
Provide version numbers for the following components (information can be retrieved by running tns info in your project folder or by inspecting the package.json of the project):

• CLI:
• Cross-platform modules: 6.2.0
• Android Runtime: 6.2.0
• iOS Runtime (if applicable):
• Plugin(s):

Describe the bug
When starting app that has android.content.ContentProvider as in the simplest way I could find Android explodes with RuntimeException as below:

To Reproduce
Extend android.content.ContentProvider with any content and try to start the app.

Expected behavior

• App does not crash
• Content provider query is being called to get the directory

Sample project
Demo project based on "Plain JavaScript -Hello World" template

Additional context
I managed to have it working using pure Android without problems and I copied the fragments of AndroidManifest.xml from it.
