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:

Process: org.nativescript.testprovider, PID: 8272

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.

Riproduci il crash con la demo nativescript-content-provider collegata e il relativo AndroidManifest.xml, partendo dall’estensione ContentProvider e dallo stack trace di Runtime.initInstance. Confronta il comportamento di NativeScript con l’esempio funzionante di puro Android del segnalante; il lavoro è concluso quando l’app si avvia senza crash e viene chiamata la query del ContentProvider per ottenere la directory.
