Getters/setters don't work with spies

[fearphage]

Problem:

The following line throws, because sinon.wrapMethod gets passed the entire property descriptor ({get, set, enumerable, configurable}) and attempts to wrap every "method" (read: property) in the descriptor.

var spy = sinon.spy(object, "property", ["get"]);

The first one to throw is set which is undefined.

Side note: I don't see any documentation about getters/setters spies and stubs anywhere.
