bug: Viewing anonymous questions/answers causes crash on frontend

[Revyy]

Anonymous questions and answers causes an error in Backstage if the person viewing the question is not the author of the question.

The culprit seems to be this line const { primaryTitle: userName } = useEntityPresentation(entityRef); in UserLink

useEntityPresentation expects a valid entity reference I suppose and since the anonymous check is executed after then it gets passed the string 'anonymous' and crashes.

Moving the if (entityRef === 'anonymous') above useEntityPresentation works but the linter will complain about that since useEntityPresentation is a react hook.

I can create a PR with a possible fix.

@Revyy can you verify the fix in the new release so we can close this? Thanks!
