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.

* Revert "This fixes an issue with a custom title-view (which has a title and a subtitle) appearing at the left side of the nav-bar instead of the center during a transition animation: when a screen with this title-view is being pushed or when you pop back to it. (#2384)"

This reverts commit 3f7f6c2612.

* Revert "Now allowing the custom nav bar to take up the whole space on iOS (#2306)"

This reverts commit 74a02ccfc5.

* adds shadow opacity, shadow color, shadow offset, shadow radius to navbar for ios

* mentions ios shadow in styling-the-navigator docs

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.
