@ehuss @weihanglo I'm not sure how to fix the your test. With this PR are no longer suggesting inside the macro, which is exactly what your test was testing. Any idea how to fix it/unblock this PR?

We are also generating a FWC warning, but that's not the real issue.

### What does this PR try to resolve?

This PR changes the triggering `rustc` lint in the
`fix_only_once_for_duplicates` test from `unused_must_use` to
`forgetting_references`, because we are changing in
rust-lang/rust#143030 the interaction between
that lint and macros.

This is required as it blocking the rust PR,
rust-lang/rust#143030 (comment).

### How to test and review this PR?

Look at the test changes.
