This fixes two problems with the autofixes for the `unused_imports`
lint:
- `use std::collections::{HashMap, self as coll};` would suggest, when
`HashMap` is unused, the incorrect `use std::collections::self as coll;`
which does not compile.
- `use std::borrow::{self, Cow};` would suggest, when `self` is unused,
`use std::borrow::{Cow};`, which contains unnecessary brackets.
