Subject: [PATCH] fix(ios): apply the travel mode to the navigation session

The travel mode passed in routingOptions or routeTokenOptions was only set
on the map views registered at that instant, never on the
GMSNavigationSession whose navigator computes the route. When
setDestinations runs before the NavigationView has attached to the session,
which is the case for the first request after a launch when the view mounts
in the same commit, the session keeps its default of driving and a cycling
or walking request comes back as a driving route.

Set the mode on the session before updating the views, and have a view that
attaches later take the session's mode instead of a fresh map view's default.
