MapView getLayer(layerId) fails for Layers with multiple dataSources

[TheRestOfMe]

For Layers using multiple dataSources, searching for a layer based on layerId fails. Specifically, in CesiumView onClick():

osh-js/source/core/ui/view/map/CesiumView.js

Line 250 in 03515e3

const layer = that.getLayer(layerId);

Calls MapView:

osh-js/source/core/ui/view/map/MapView.js

Line 248 in 03515e3

getLayer(layerId) {

Which is returning null.
