@jdonszelmann This PR does not introduce the bug, it merely finds it. I think it's better to fix it in a separate PR, since the fix is sadly not trivial

Warn on unused_attributes in uitests

r? `@jdonszelmann`

Because:
- unused_attributes warnings are usually actual mistakes, rather than just unused code, and we want to notify test writers they may be accidentally making a mistake
- Because the lint was allowed by default previously, we missed real bugs, because the test coverage is worse
