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

Start by reproducing tns build android --bundle --clean and compare the logged steps for the clean and build phases. Trace the clean-task entry point and determine why build-task logic runs during cleaning; done means clean no longer performs unnecessary build steps while the normal build output remains unchanged.
