Switching from 2D to 3D activity if a GeoJson layer is visible raises an error

[claustres]

The following error is raised when switching from 2D to 3D activity if a GeoJson layer has been imported and is visible: TypeError: Cannot read property 'features' of undefined.

Linked to kalisio/kdk#328.

What happens is destroyed gets called from mixin.base-map which calls this.map.remove()
this.map.remove() iterate over it's layer calling remove() on them
Realtime layer's remove method expects a geojson parameter which is then undefined, generating an exception.

We probably should clear the map before this.map.remove() in mixin.base-map destroyed.

The layer on which the error occurs is the selection layer that is added by mixin.feature-selection

Right, the issue has been identified in kalisio/kdk#328, waiting for maintainer feedback.

What is strange is that the map should have been already cleaned here but it seems the layer is still referenced in Leaflet.

Seems to be closed now, possibly linked to kalisio/kdk#328.
