Remove from_method symbol

Fixes rust-lang#113439

`on_unimplemented_note` was calling `item_name` for RPITITs and that produced ICEs. I've added a regression test for that but also have removed `from_method` symbol entirely because it wasn't even used and by doing that the `item_name` call was also removed.
