Title: 204 response from server can't remove unsavedclass

If responding with 204, params.response is undefined so `sent` var is still false.
Fix by ignoring savenochange option when determining whether a request is sent.

This will fix https://github.com/bootstrap-ruby/bootstrap-editable-rails/issues/21.
