Describe the bug unit testing for freshly created angular project is broken on android

To Reproduce run commands

$ tns create demo-mocha-tests-ng --ng
$ tns test init

select mocha

$ tns test android

after running test application run is failed $ tns run android see screenshot above app can be run only after command $ tns platform clean android

Expected behavior example test should run on android

Thank you. When I added suggested line to App_Resources/Android/src/main/AndroidManifest.xml I was able to run example test but when I created a simple typescript test:

import { AppComponent } from '../app/app.component';

// application test
describe('Import Statement', function () {
		it('should be possible to add import statement', function () {
			const app = new AppComponent();
			chai.assert.equal(true, true);
		});
});

the run fails

I see two issues reported above:

1. Unit testing do not work on new NG projects (because nsconfig is not respected)
2. tns run after tns test require platform clean

Issue #1 is fixed in nativescript-unit-test-runner@0.4.1 and nativescript@next (will be shipped in 5.2.0).

Issue #2 is duplicate of https://github.com/NativeScript/nativescript-cli/issues/3146#issuecomment-457686993
