When using the JS API, GeoJSON layers only show the last 2 geometries

[mbarto]

Description

This is caused by a bug in the leaflet implementation of the Feature component. The problem is here: https://github.com/geosolutions-it/MapStore2/blob/master/web/client/components/map/leaflet/Feature.jsx#L113

Using a lodash deepClone instead of the JS spread operator solves the issue (the style object is not a simple value object, but a class in a complex hierarchy, so properties are in nested prototypes and are not copied by the spread operator).

How to reproduce

Create a JS API app and add the following trigger:

MapStore2.triggerAction({
            type: 'ADD_LAYER',
            layer: {
                "type" : "vector",
                "name": "TestJSON",
                "visibility": true,
                "features" : [
                  {
                    "type": "Feature",
                    "id":1,
                    "geometry": {
                        "type": "Point",
                        "coordinates": [11,44]
                    },
                    "properties": {}
                  },
                  {
                    "type": "Feature",
                    "id":2,
                    "geometry": {
                        "type": "Point",
                        "coordinates": [12,44]
                    },
                    "properties": {}
                  },
                  {
                    "type": "Feature",
                    "id":3,
                    "geometry": {
                        "type": "Point",
                        "coordinates": [13,44]
                    },
                    "properties": {}
                  },
                  {
                    "type": "Feature",
                    "id":4,
                    "geometry": {
                        "type": "Point",
                        "coordinates": [14,44]
                    },
                    "properties": {}
                  }
                ]
            }
        });
