Setting muteVoiceGuidance(false) in OptionsBuilder does not unmute

Android API: 29
Mapbox Navigation SDK version:1.6.1

Steps to trigger behavior

If muteVoiceGuidance is previously set to true and then you try try to set it to false this does not do anything and the voice guidance remains muted.

I believe this is due to the following code in NavigationView https://github.com/mapbox/mapbox-navigation-android/blob/a4a244c37507a551ecb58cdccc910899f7547d1f/libnavigation-ui/src/main/java/com/mapbox/navigation/ui/NavigationView.java#L966

  private void initializeVoiceGuidanceMuteState(@NonNull final NavigationViewOptions options) {
    if (options.muteVoiceGuidance() && !isVoiceGuidanceMuted()) {
      navigationViewModel.setMuted(((SoundButton) retrieveSoundButton()).toggleMute());
    }
  }

This only runs if muteVoiceGuidance is true. When it's false there is no code to set the mute status on the navigationViewModel back to unmuted.

Expected behavior

Setting muteVoiceGuidance(false) should unmute the voice guidance and voice instructions should be played.

Actual behavior

Voice instructions remain muted.

Start in libnavigation-ui/src/main/java/com/mapbox/navigation/ui/NavigationView.java at initializeVoiceGuidanceMuteState, and inspect how NavigationViewOptions, navigationViewModel, and SoundButton represent mute state. Reproduce changing muteVoiceGuidance from true to false; done means voice guidance is unmuted and voice instructions play.
