Model.destroy() errors out in Backbone.sync

[sderickson]

TypeError: Cannot read property 'wait' of undefined

The problem appears to be the replaced Backbone.sync function:

Backbone.sync = (method, model, options) ->

Call options.success() callback to trigger destroy event which triggers

synchronization to other browsers.

if method is "delete"
options.success()

And that goes to this function wrapper in Backbone 0.9.10:

  options.success = function(model, resp, options) {
    if (options.wait || model.isNew()) destroy();
    if (success) success(model, resp, options);
  };

Since no parameters are passed to options.success(), options is undefined and options.wait throws an error (as would model.isNew if given the chance).

Changing that line to:

options.success(model, null, options)

Seems to do the trick. Now destroy() doesn't error out for me.
