Bug: FtcrNavigationManager the language changes after reroute in listener

[Strikelon]

Describe the bug
We use FtcrNavigationManager, before calculating new route, I create routeOptions with languafe French. After route is calculated, and navigation is started, everything is ok, the language is French. But we listen a reroute event in the navigation listener, and when it comes, and I start the navigation with the new route from the listener, it speaks with English Language.

private val routeOptions = FTCRRouteOptions().apply {
    setUseTraffic(true)
    routeType = FTCRRouteOptions.Type.FASTEST
    transportMode = FTCRRouteOptions.TransportMode.CAR
    addParameter(LANGUAGE_ROUTE_OPTIONS_KEY, LANGUAGE_ROUTE_OPTIONS_FRANCE)
    addParameter(VEHICLE_TYPE_PARAMETR_TITLE, VEHICLE_TYPE_PARAMETR_VALUE)
}

Steps To Reproduce
Steps to reproduce the behavior:

1. create
   private val routeOptions = FTCRRouteOptions().apply {
   setUseTraffic(true)
   routeType = FTCRRouteOptions.Type.FASTEST
   transportMode = FTCRRouteOptions.TransportMode.CAR
   addParameter("language", "fr-fr")
   addParameter("algopts", "vehicleType:taxi")
   }
2. calculate route
3. add FTCRNavigationManager.FTCRNavigationManagerListener to navigator
4. start navigation, language is French it is ok
5. deviate from the route
6. get new route in event onRerouteEnd in FTCRNavigationManager.FTCRNavigationManagerListener
7. start navigation with new route
8. The language is English, not French, I think because all FTCRRouteOptions skips

Expected behavior
language is French and other FTCRRouteOptions are saved during reroute in listener
