Gradle clean task executes not needed steps

まず tns build android --bundle --clean を再現し、clean フェーズと build フェーズでログに記録された手順を比較します。clean-task のエントリポイントを追跡し、なぜクリーニング中に build-task のロジックが実行されるのかを特定します。clean が不要な build 手順を実行しなくなり、通常の build 出力が変わらなければ完了です。

Environment

• CLI: 5.3.2
• Cross-platform modules:
• Android Runtime: 5.3.1
• iOS Runtime (if applicable):
• Plugin(s):

Describe the bug

Gradle clean...
         + setting applicationId
         + applying user-defined configuration from /Users/myUser/Work/nativescript-cli/scratch/buildProject/app/App_Resources/Android/app.gradle
         + using support library version 28.0.0
         + adding nativescript runtime package dependency: nativescript-optimized-with-inspector
         + adding aar plugin dependency: /Users/myUser/Work/nativescript-cli/scratch/buildProject/node_modules/tns-core-modules-widgets/platforms/android/widgets-release.aar
Gradle build...
         + setting applicationId
         + applying user-defined configuration from /Users/myUser/Work/nativescript-cli/scratch/buildProject/app/App_Resources/Android/app.gradle
         + using support library version 28.0.0
         + adding nativescript runtime package dependency: nativescript-optimized-with-inspector
         + adding aar plugin dependency: /Users/myUser/Work/nativescript-cli/scratch/buildProject/node_modules/tns-core-modules-widgets/platforms/android/widgets-release.aar

As you can see from the above log, the output from Gradle clean... and Gradle build... is the same. Most probably we don't need to execute build task's logic when cleaning the project.

To Reproduce
tns build android --bundle --clean
