Description

System webhooks (added with #10546) trigger when you create a new repository but not when you migrate a repository.

Steps to reproduce

• Compile and run a local Gitea
• Start a web server that will log webhook attempts, e.g.

$ python3 -m http.server
Serving HTTP on 0.0.0.0 port 8000 (http://0.0.0.0:8000/) ...

• Go to http://localhost:3000/admin/system-hooks and add a system webhook, for all events

• Add a new repository, see that the web server logs them (the 501 error is expected)

127.0.0.1 - - [15/Dec/2020 14:30:05] code 501, message Unsupported method ('POST')
127.0.0.1 - - [15/Dec/2020 14:30:05] "POST / HTTP/1.1" 501 -

• Migrate a repository and observe that no request is sent and nothing is logged on the webserver.
