[NS7] Initial project fails to build production release

Environment

• CLI: 7.0.8
• Android Runtime: 7.0.0

Describe the bug
running ns build android --release --env.snapshot --env.compileSnapshot --env.uglify --keyStorePath <KEYSTORE> --keyStorePassword <PASSWORD> --keyStoreAlias <ALIAS> --keyStoreAliasPassword <PASSWORD> --aab

throws

/test-project/node_modules/webpack-cli/bin/cli.js:93
				throw err;
				^

Error: In order to generate a V8 snapshot you must have the "android" platform installed - to do so please run "tns platform add android".
    at NativeScriptSnapshotPlugin.ProjectSnapshotGenerator.validateAndroidRuntimeVersion (/test-project/node_modules/@nativescript/webpack/snapshot/android/project-snapshot-generator.js:124:15)

Adding this to package.json resolves the error but I think it's not intended to be like that in NS7:

  "nativescript": {
    "id": "io.thisapp.thisappmap",
    "tns-android": {
      "version": "7.0.0"
    }
  },

To Reproduce

• Initialize a new project
• Run the command mentioned above

NativeScript CLI 7.0.8 と Android Runtime 7.0.0 を使用し、初期化直後のプロジェクトで報告されたコマンドを再現します。node_modules/@nativescript/webpack/snapshot/android/project-snapshot-generator.js にあるスタックトレースのパスを起点にし、生成された package.json の nativescript 設定と比較します。tns-android のバージョンを手動で追加せずにリリース AAB ビルドが成功すれば完了です。
