Subject: [PATCH] Fix FineUploader to handle cancellations in the onError()
 callback
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Calling cancel() in the onError() callback would cause an error as the
upload handler tries to clear the upload’s xhr requests after cancel
already clears them.
