alekhurst 55ce19d84e Change gesture direction strings in NavigatorSceneConfigs
Summary:
I see there is a string matching inconsistency in  `Libraries/CustomComponents/Navigator/Navigator.js` and `Libraries/CustomComponents/Navigator/NavigatorSceneConfigs.js`, which caused a bug resulting in gestures not working for vertical SceneConfigs. This PR fixes the inconsistency, and the bug.

var isTravelInverted =
