Prevent fatal error if the revision has no author

Patch still applies and we have been using it in production sites for a while.

Would be great to have it merged.

Marking as RTBC.

Thanks for the work on this one. I've recently taken up maintainership of this project and am looking through the RTBC issues.

This fix looks good.

To get this in, I'll need an MR rebased against the latest 8.x-1.x code with tests added.

Thanks!

Hello, I have raised MR for the same.

Don't remove the tag if tests haven't been added please.
