Describe the bug
While updating / migrating my project to v7 typescript will get set to version 3.9.7 to be complaint for v7.
This leads to an issue when starting the application.

ERROR in The Angular Compiler requires TypeScript >=3.4.0 and <3.6.0 but 3.9.7 was found instead.

When now downgrading "typescript": "3.5.3", we will receive an error message that the application is not compatible anymore.

splash34$ tns debug android
The current application is not compatible with NativeScript CLI 7.0.

Run 'ns migrate' to migrate your project to NativeScript 7.

Alternatively you may try running it with '--force' to skip this check.

Setup project with following dependencies:

"dependencies": {
    "@angular/animations": "10.1.0",
    "@angular/common": "10.1.0",
    "@angular/compiler": "10.1.0",

  }

Expected behavior
Start application after upgrade with emulators.

Bắt đầu với các phiên bản dependency trong package.json và tái hiện lỗi bằng tns debug android. Kiểm tra quá trình kiểm tra khả năng tương thích của CLI và đường dẫn ns migrate để xác định NativeScript CLI 7.0.6 xử lý các yêu cầu của Angular Compiler và TypeScript như thế nào; được xem là hoàn tất khi một project được migrate đúng cách có thể khởi động mà không gặp lỗi phiên bản xung đột.
