Gradle clean task executes not needed steps

Environment

• 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

Beginne damit, tns build android --bundle --clean zu reproduzieren, und vergleiche die protokollierten Schritte für die Clean- und Build-Phasen. Verfolge den Einstiegspunkt der Clean-Task und ermittle, warum die Build-Task-Logik während des Bereinigens ausgeführt wird; fertig ist die Arbeit, wenn clean keine unnötigen Build-Schritte mehr ausführt und die normale Build-Ausgabe unverändert bleibt.
