[Bug]: Navigation spams route alternatives each second

@kried is already working on this.

Since Oct 30, 2023.

### Mapbox Navigation SDK version

2.17.0

### Steps to reproduce

Start a step by step navigation which has alternative routes displayed on the mapview. The navigation will startstuttering / flashing the route. Checking the logs will show you that the reroutes get spammed each second.

### Expected behavior

The Navigation Controller should do nothing when the user is not moving. No alternatives should be selected or removed.

### Actual behavior

The Console spams this:

`[Info, nav-native]: RouteAlternativesControllerImpl::onStatus alternatives=[ ], removed=[ altId=309(routeId=HhZKQhlziKK239kZfzHh9azxoYxAL7zU5UZDwew0jV5awfLuAlvlEQ==_eu-west-1#1) ]

This just keeps going about once each second, even if the user does nothing, does not touch the screen or move in any way. The Route Layer begins flashing and the map stutters on each reload. I have noticed that it stops once the user manually selects one of the route alternatives. The navigation controller then stops automatically switching alternative.

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