I just make a demo to publish crates name with h2-demo.

• But when first exec cmd:cargo publish --registry=mycrates
  with version:0.1.0 Success.
• When Cargo.toml version not changed, I just try exec cmd again:cargo publish --registry=mycrates,that publish response error,the message is :

error: failed to get a 200 OK response, got 500
headers:
	HTTP/1.1 100 Continue



	HTTP/1.1 500 Internal Server Error
