Hedger Wang f7279b4074 Remove key from NavigationState.
Summary:
NavigationState is composed of many things such as `index`, `routes`.
The only way to effectively compare navigation states is to assume their immutability
and simply compare their references.

That said, `navigationState.key` does not really serves anything useful. The key does
not make a navigation state more unique or comparable.

This diff makes  `navigationState.key` irrelevant thus we could make NavigationState
simpler.
