android plugins built multiple times

my material components all depend on @nativescript-community/ui-material-core.
If you build an app using multiple of them you ll see something like that
We should only need to build it once.

That app shows that behavior: https://github.com/nativescript-community/ui-material-components/tree/master/demo-vue

從 issue 中連結的 demo-vue 應用程式開始，使用多個 Material 元件重現其 Android 建置。追蹤 @nativescript-community/ui-material-core 和 before-plugins.gradle 的處理位置；當共用 core AAR 只建置一次，同時相依的外掛程式仍能成功建置時，即表示完成。
