Subject: [PATCH] <Navigator />: Fix the getter for `navigationContext`.

Summary:
@public
The current getter for `navigationContext` always return a static
context, and it should return an instance-based one, instead.

Test Plan:
Use console.log() in inspect that two different navigators do
have their own `navigationContext` created.
