Fix WebView Memory Leak in GutenbergView (#156)

* Don't set api namespace for remote config in Android demo app

* Fix WebView memory leak by adding destroy() call to onDetachedFromWindow()

WebViews were lingering in Chrome inspector after closing the editor because GutenbergView.onDetachedFromWindow() cleaned up listeners but didn't call WebView.destroy(). Adding this.destroy() ensures WebViews are properly disposed of when detached from the window hierarchy.
