cubicweb #724769 Use RemoteCallFailed in the publisher's error_handler [resolved]

On an ajax request, if a ValidationError occurs during the publisher's commit, it will raise a StatusResponse(500) but a RemoteCallFailed(exc) would be more appropriate since it would make the error appear automatically on the web page as a standard error message.
