fixed crash in android, layer not added in maps with 3D themes

Description

Using 3D themes in mapbox causes a crash in android devices. The layer index is not calculated correctly and can not be added.

The fix is to add a new layer when the calculated index is negative.

hi @mfazekas it occurs exclusively on a client-specific map, which I cannot share due to proprietary restrictions.

closed, the issue is fixed not using anymore layerIndex in the RN components. We use instead only aboveLayerID and belowLayerID to set the layer position in the map.
