[Bug]: When simulation starts under `inTunnels` mode the `NavigationService` failed to send out notification

Mapbox Navigation SDK version

v2.1.1

Steps to reproduce

1. Open Example, set the navigationViewController.navigationMapView?.userLocationStyle = .puck2D()
2. Set the location to a still customer location, build the app.
3. Unselect the simulationButton, to choose the inTunnels simulation mode.
4. start navigation and wait till the simulation start

Expected behavior

The map puck will move because the NavigationService.simulate(intent:) is called to send out notification of simulation starts, and the NavigationViewController could set up simulated location provider for map puck.

Actual behavior

The map puck is stale because NavigationService.simulate(intent:) is not called.

Is this a one-time issue or a repeatable issue?

repeatable

Start with NavigationService.simulate(intent:) and the inTunnels simulation path described in Example, then compare it with the simulationButton path. Reproduce the stale puck behavior and trace whether the simulation-start notification is sent. Done means the inTunnels path notifies NavigationViewController so the simulated location provider can update the map puck.
