Android：FlutterBoostFragment 里面有PlatformView时候，切到另外一个Tab的FlutterBoostFragment 会crash

## Steps to Reproduce
1.在 flutterboost example工程 修改 “main dart”，
把tab_message修改调到example工程里面的NativeViewExample页面
`

tab_message': (settings, uniqueId) {
return PageRouteBuilder(

settings: settings,

pageBuilder: (_, __, ___) =>

NativeViewExample());

}
`
2. run example 工程起来 进入 “open flutter fragment page”
3. 切换到 朋友Tab 必崩

Reproduce the crash in the example project's main.dart using NativeViewExample and switching to the Friends tab. Start from FlutterBoostFragment.onCreateView and the PlatformViewsController.attachToView stack-trace entry. Done means switching between FlutterBoostFragment tabs with a PlatformView no longer throws the child-already-has-a-parent exception.
