Summary: in FlipperRSocketResponder::handleFireAndForget, a responder object was being conditionally (for requests with an "id" field) created, resulting in a null pointer passed into FlipperClient::onMessageReceived when no id was present. FlipperClient::onMessage received, in the meantime, unconditionally dereferences that pointer, resulting in a segmentation fault. This change creates the responder object regardless of whether or not the "id" key is present in the request object, thus avoiding passing a null pointer into FlipperClient::onMessageReceived.
