Merging of Service.AccessoryInformation breaks later updates to it's characteristics

[FrodoKenny]

In Server.prototype._createAccessory a potentially supplied AccessoryInformation from the getServices of an Accessory is merged with the default one from the constructor. Because the reference from the constructor is kept instead of the one from getServices, it is not possible to update the Characteristic.Model etc. with a setValue after a callback, using the reference from getServices.

Can it be changed to keep the reference from getServices and merge the default fields into that one?
