	Currently the `POST /repos/{owner}/{repo}/contents` API endpoint accepts request without any `ChangeFileOperation.SHA`, unlike stated by the doc:
33eee199cf/modules/structs/repo_file.go (L80-L81)
This PR adds:
- some more (already passing) tests around this function
- a new (failing) test to show this wrong behavior
- a fix (note that this is a breaking change for clients exploiting this bug)
- an update for all the existing tests
