TBA: Delete SyncPreference from tablet layout
We already deleted it in preferences_general.xml, but we should delete it in mobile/android/app/src/main/res/xml/preferences_general_tablet.xml
, too.
<org.mozilla.gecko.preferences.SyncPreference android:key="android.not_a_preference.sync"
android:title="@string/pref_sync"
android:persistent="false" />
