Adam Comella 54e947152f Navigator: null check on gesture.overswipe to prevent crash ...

Summary:
Sometimes, `gesture.overswipe` can be `null`/`undefined` in `_moveAttachedGesture` resulting in a crash. This change adds a null check to avoid the crash. `_matchGestureAction` has a similar check so it looks like this case was overlooked in `_moveAttachedGesture`.

**Test plan (required)**

My team's app is using this change.
