    Prevent crash when adding unmanaged fragment in nav
   
    Currently, if you attempt to add a fragment to the fragment manager
    associated with the FragmentNavigator, navigation crashes as it cannot
    find an entry associated with fragment.
   
    While it is strongly recommended to only use navigation APIs to
    manipulate the fragment manager, if the back stack is not affected, then
    we should not crash.
   
    RelNote: "Adding fragments to the `FragmentNavigator`'s
    `FragmentManager` without using navigation will no longer crash."
    Test: Added FragmentNavigatorTest
