On Android the Refresh message is not being disposed

[josesimas]

Hello,

On the MapViewRenderer for iOS the Dispose method is overriden and the Refresh message is unsubscribed. This is missing on the Android MapViewRenderer. In my tests this message was not cleared in OnElementChanged and I had to add:

protected override void Dispose(bool disposing)
{
    MessagingCenter.Unsubscribe<MapView>(this, "Refresh");
    base.Dispose(disposing);
}

Maybe this should not be an issue but since you are moving on to a new implementation I thought I would leave this here in case someone finds it useful.
