At the moment, the annotations implementation in the `mapbox-gl-native` core is creating concrete layer instances apart from `LayerManager/LayerFactory` code path. So, annotations must be disabled if the `LayerManager` implementation does not provide line, fill or symbol layers (those, used by the annotations). Note: in future, annotations implementation will be moved from the core to the platform SDK level(see https://github.com/mapbox/mapbox-plugins-android/tree/master/plugin-annotation) and `LayerManager` won't need to disable it.
