[ReactNative] Fix Navigator empty scene issue 

Summary:
In some situations, when quickly swiping back to a scene we are transitioning from, the scene is blank/missing. This is fixed by adding a check for the active gesture when we hide the scenes.

@public

Test Plan: Can no longer reproduce on simulator when quickly swiping back to the scene we are transitioning from
