Removing plugin which has dependencies with native code won't clean the platform

Problem:

Installing a plugin, which depends on other plugins with native dependencies will not trigger a platform clean (especially necessary when building for android) when removed.
Suppose we have tns-core-modules, which is purely javascript. It depends on tns-core-modules-widgets which comprises of native android and iOS plugins.
tns-core-modules
'--tns-core-modules-widgets

Versions:

CLI: 2.5
Android runtime: 2.5/3.0
modules: any version

Steps to reproduce:

tns create myTestApp
cd myTestApp
tns build android <- at this point tns-core-modules are added as a dependency
The build process will generate build artifacts with the specific version of its native dependencies (tns-core-modules-widgets) This can be verified by finding tns-core-modules-widgets inside the 'platforms/android/configurations' dir.
tns plugin remove tns-core-modules <- will not trigger gradle clean - https://github.com/NativeScript/nativescript-cli/blob/master/lib/services/android-project-service.ts#L377

从 lib/services/android-project-service.ts 第 377 行附近开始，复现列出的 Android 构建和移除插件步骤。检查移除 tns-core-modules 前后的 platforms/android/configurations；当移除操作触发 platform clean，使原生依赖项工件不再保留时，即表示完成。
