`default_trait_access` autofix not working

Description

Hi

I find clippy very very useful and one lint I get a lot is default_trait_access. For some reason, it doesn't autofix when this is available even though the fix is suggested.

It's implemented here, but there's a comment that references a TODO that doesn't seem to exist:
https://github.com/rust-lang/rust-clippy/blob/e52501913b75235e3d41422566a2d05d6f00b699/clippy_lints/src/default.rs#L97-L105
This was authored by @flip1995 (perhaps you can help)?

There's also this suspicious file with errors tests/ui/default_trait_access.rs and fixes tests/ui/default_trait_access.fixed, so maybe my settings aren't correct.

Please, let me know and I'd be happy to implement this once the mysterious TODO comment is resolved.

Start in clippy_lints/src/default.rs around the default_trait_access implementation and inspect the TODO comment. Compare tests/ui/default_trait_access.rs with tests/ui/default_trait_access.fixed, then run the relevant UI test to reproduce the missing autofix. Done means the suggested default_trait_access change is applied correctly and the regression coverage passes.
