[patch][cla] ServiceStore does not pass fetch request object to onError callback

[avoidscorn]

The dojo.data.api.Read documentation for the fetch method says that the onError callback will be passed two arguments: an Error object and the Request object. However, ServiceStore only passes the Error object to the onError callback.

The DataGrid widget expects a valid Request object in its onError callback and will throw a TypeError if the Request argument is undefined. The exception is swallowed by the deferred, but the grid is left in an invalid state (it will refuse to refresh itself from that point on).

The attached patch resolves the issue for me.
