Fix #9771 (`unnecessary_to_owned` false positive)

Fixes #9771

In that issue's example(s), the lint tried to add a `&` to a value, which implicitly changed the type of a field to a reference. The fix is to add the reference to `receiver_ty` (the type of the receiver of the `to_owned`-like method), before passing `receiver_ty` to `can_change_type`. `can_change_type` properly rejects the modified `receiver_ty`.

cc: `@mikerite` just because I think he was the author of `can_change_type`.
