Attributions are not shown is the attribution control is added after layers

[Zverik]

1. Initialize L.Map with an option attributionControl: false
2. Add layers
3. map.addControl(L.control.attribution())

Result: only 'Leaflet' is shown in attribution. Expected result: the correct attribution for all layers.

(also, prefix in api docs is outdated)

Will check it out, thanks.

BTW what's the use case of adding it later?

I encountered this when I made a subclass of attribution control. Some frameworks may offer an empty leaflet panel with no default controls.
