Fix regression involving custom derives on items with `$crate` The regression was introduced in #37213. I believe we cannot make the improvements from #37213 work with the current custom derive setup (c.f. https://github.com/rust-lang/rust/issues/37637#issuecomment-258959145) -- we'll have to wait for `TokenStream`'s API to improve. Fixes #37637. r? @nrc
