When disabling elevation by setting topBarElevationShadowEnabled to false, this commit allows to re-enable it by setting the same property to true.
Elevation was previously disabled by using setOutlineProvider(null), with ViewOutlineProvider being an Android 5.0+ object responsible for determining how views draw their outline. To allow re-enabling elevation, we keep our original ViewOutlineProvider and restore it when elevation is enabled again.

This happens because the title-view is being created again when RVVViewController appears. There's probably no point in setting the title-view again with the same data when it already has it. The title view setup is done anyway in RCCNavigationController.

This can be easily reproduced by calling "this.props.navigator.setSubTitle({subtitle: 'a subtitle'});" from the constructor of a pushed screen.
