ScrollView's scrollToEnd scrolls too far on android

Description

ScrollView's scrollToEnd method gives different results on iOs and Android.

Expected behaviour:
ScrollView's scrollToEnd method should function consistently across platforms. Ideally The view should scroll until the bottom of the content reaches the bottom of the view.

Actual behaviour:
On iOs the view tries to scroll until the bottom of the content reaches the bottom of the view.
On Android the view tries to scroll until the bottom of the content reaches the top of the view.

This is especially annoying if you add content while the view is scrolling, as it then scrolls too far, or if you have an animation of content being added to slide in from the bottom.

Steps to reproduce

1. Open the provided snack on Android
2. Press the button labeled "Press me!"
3. The view scrolls until element "Test 50" reaches the top of the screen
4. Open the provided snack on iOs
5. Press the button labeled "Press me!"
6. The view scrolls until element "Test 49" reaches the bottom of the screen

提供された再現手順と ScrollView's scrollToEnd の Android 実装から始め、その挙動を issue に記載された iOS の結果と比較します。スクロール中にコンテンツが追加された場合の挙動を確認します。既存のテスト構成で対応できる場合はリグレッションテストのカバレッジを追加し、Android が iOS と一貫してコンテンツの下端をビューの下端に揃えた状態で停止すれば完了です。
