LocationLayerController layer map memory leak

[dsuresh-ap]

Steps to reproduce

1. Activate location component
2. Set different styles
3. Old layers aren't removed from layerMap in `LocationLayerController'

Expected behavior

New ids will only be added if they weren't already in the list.

Actual behavior

The only time ids are cleared is applyStyle is called.

private void addLayerToMap(Layer layer, @NonNull String idBelowLayer) {
    style.addLayerBelow(layer, idBelowLayer);
    layerMap.add(layer.getId()); // Ids keep getting added
  }
