[web] Only log exceptions in debug mode in Ajax controllers
When we raise a RemoteCallFailed error (erroneously turned into a '500
Internal Server Error' response, but that's another business). In production
environment, we do not want to log the exception in most cases where it's
actually a client error. So only log the exception in debug mode.
