Remove events in the latest leaflet build

[koppelbakje]

Since Leaflet/Leaflet@a1acaff there are two more conditions added in the last if-statement removeEventListener function. When the contextId is undefined the events won't be removed. It should be solved by passing the marker its context to the off calls in the removeHooks.

removeHooks: function () {
        L.Draw.Feature.prototype.removeHooks.call(this);

        if (this._map) {
            if (this._marker) {
                this._marker.off('click', this._onClick, this);
                this._map
                    .off('click', this._onClick, this)
                    .removeLayer(this._marker);
                delete this._marker;
            }

            this._mouseMarker.off('click', this._onClick, this);
            this._map.removeLayer(this._mouseMarker);
            delete this._mouseMarker;

            this._map.off('mousemove', this._onMouseMove, this);
        }
    }

EDIT: besides Draw.Marker the similar problem also existed in Draw.PolyLine, EditToolbar.Delete and EditToolbar.Edit
