Gradle clean task executes not needed steps

首先重现 tns build android --bundle --clean，并比较 clean 阶段和 build 阶段记录的步骤。跟踪 clean-task 的入口点，确定为什么在清理过程中会运行 build-task 逻辑；完成的标准是 clean 不再执行不必要的 build 步骤，同时正常的 build 输出保持不变。

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
