Some notes:
- I didn't write integration tests because it's a pure bugfix that addresses implementation details of the model layer.
- I can see interpretations of "it involves interactions with a live Forgejo server" that would cover this PR, but they don't make sense to me in context.
- I didn't add anything to the documentation because it's a pure bugfix - the system should always have worked this way
- there's no value in confusing people trying to figure out how the system works now with how it didn't work in the past
- However, there IS value in informing people who may have gotten bitten by this in the past, so I think a release note makes sense
- These fixes are closely related, and the changes small, so I decided to make just one PR.
- From a user perspective, this is just one issue, and I think in terms of release notes, it makes more sense to have just this one.
- Technically, fixing only one of the underlying issues would be enough. Since this is a case of invalid states being representable, it makes sense to both try to prevent it happening in the first place, and deal with it gracefully if it does happen.
- At the very least, fixing #12245 is required unless we want to live with data generated in the past being broken
