Icon is reset on cluster marker when nothing has changed

[ccjenkins14]

I am able to encounter a case where cluster.hashCode !== data._leafletOldHashCode , causing the icon to be reset, however, there is no discernible difference between the cached clusters except for the hash code.

Lines 397 - 404 of LeafletAdapter.js

// Update the icon if the population of his content has changed or if we need to reset the icon
if (resetIcons || cluster.population != data._leafletOldPopulation ||
	cluster.hashCode !== data._leafletOldHashCode) {
	var boundsCopy = {};
	L.Util.extend(boundsCopy, cluster.bounds);
	(<any>oldMarker)._leafletClusterBounds = boundsCopy;
	oldMarker.setIcon(this.BuildLeafletClusterIcon(cluster));
}

I am using bower package version 2.1.0.
