ns 9 running test after running the app starts the app not the test runner.

Issue Description

When I create a new NativeScript 9 Angular App using ns create and I add tests using ns test init then I run the app using (e.g.) ns run android, stop it and run the tests with (e.g.) ns test android the App is launched on my emulator instead of the test runner.

The issue happens on both Android and iOS. The tests run correctly if a clean is run before them.

The issue also happens on a NativeScript Angular App upgraded from 8 to 9, which worked correctly before the upgrade to 9.

The issue is reproduced with an Angular App that uses Jasmine as its test framework, it does not appear that test framework should make a difference but other test frameworks have not been checked.

There are historical issues with this happening on NativeScript apps before version 9. I have checked for the issues that caused this in the past and none of the fixes or work arounds apply as far as I can tell.

Reproduction

1. Install or update to NativeScript 9. I was using 9.0.6 CLI, but I have also seen the problem on older versions of 9.
2. Create a new NativeScript App with:

ns create myNewNSAngularApp

3. Choose Angular as the Framework and "HelloWorld" as the example you want to use.
4. Once created cd into the app cd myNewNSAngularApp
5. Add tests with:

ns test init --framework jasmine

6. Once created, prepare, in my case for android, with:

ns prepare android

7. Run the app with:

ns run android

8. After checking the app runs, terminate it on the emulator and in the console.
9. Run the tests with:

ns test android

10. Notice that instead of the test running, the app has restarted.
11. Clean with:

ns clean

12. Run the tests again with:

ns test android

13. Note that the test runs as expected.
