Get DynamicMapLayer.getLayers() does not return layers

[bbehling]

• Browser and version:
  Chrome 50.0.2661.102 m
• Version of Leaflet (L.version):
  1.0.0-rc.1
• Version of esri Leaflet (L.esri.VERSION):
  2.0.0
• I'm loading/bundling the library using:

ie: [CDN](https://cdn.jsdelivr.net/leaflet.esri/2.0.0/esri-leaflet.js

Steps to reproduce the error:

1. Add a dynamic layer to the map
   2.Wait for the layer to load
2. In the load callback function, call getLayers() on the dynamic layer

What happens is getLayers() returns false.

I was expecting an array of layers on the MapService that are being shown

the API reference could be a lot clearer on this, but the getLayers() method doesn't fire off a request for service metadata describing which layers are visible by default, it simply passes back information present in the layer constructor options.

my reply in issue #566 is relevant here too because i describe the same technique you'd use to fetch the layers and their default visibility.

happy to discuss this more if it'd be helpful.
