Crash: Attempt to invoke virtual method 'void com.mapbox.navigation.ui.MultiOnClickListener.clearListeners()' on a null object reference

Nadie ha tomado este issue todavía.

**Android API:**
Mapbox Navigation SDK version: **9.6.0** and Navigator **1.1.0** & **1.3.0**

### Steps to trigger behavior

1. Basically I'm using the sample from here https://docs.mapbox.com/android/navigation/guides/install/ (however it is converted into a different language).
2. Pause/Switch Application

### Expected behavior
No Crash

### Actual behavior
Crash

Appears to be like #1971, however the stack trace appears to be slightly different.

This occurs when I click the `Switch` application button (i.e. Square Nav Button); the app throws this error. I am logging all the events; and I see:
The Pause & Stop events in sequence, which I then chain to the MapBox Navigator onPause, onStop calls exactly like the demo. However about 1/2 a second after; I get the below stack trace crash.... I've also tried not sending the onStop, onPause, etc... No change...

Based on the callstack below; I suspect the issue is something has already called:
https://github.com/mapbox/mapbox-navigation-android/blob/master/libnavigation-ui/src/main/java/com/mapbox/navigation/ui/RecenterButton.java#L142-L146

And
https://github.com/mapbox/mapbox-navigation-android/blob/master/libnavigation-ui/src/main/java/com/mapbox/navigation/ui/RecenterButton.java#L144
This line I believe is actually invalid, as nothing in the code will re-create the MultiOnClickListener again in this element.
as it is only created during creation of it, so if this element is re-attached it will misbehave and crash later:
https://github.com/mapbox/mapbox-navigation-android/blob/master/libnavigation-ui/src/main/java/com/mapbox/navigation/ui/RecenterButton.java#L29

According to https://stackoverflow.com/a/65227045 & https://proandroiddev.com/make-your-custom-view-lifecycle-aware-its-a-piece-of-cake-90b7c0498686 it appears `onDetachFromWindow` is NOT the place to cleanup/null things like this, as the view can be re-attached **without** being re-created if used in things like tabs/pagers. So nulling the listener will lead to a crash if it is re-attached. In addition it might be good if you checked to verify that the `MultiOnClickListener` isn't null in the `clearListeners` function on line 143 as something obviously called this function a second time...

Comienza con libnavigation-ui/src/main/java/com/mapbox/navigation/ui/RecenterButton.java, especialmente con onDetachedFromWindow y clearListeners, y revisa el stack trace proporcionado. Reproduce el fallo cambiando desde la aplicación de navegación de ejemplo y, después, verifica que separar y volver a adjuntar la vista ya no provoque el fallo por un objeto nulo.
