ARROW-5217: [Rust] [DataFusion] Fix failing tests
Due to recent changes in the HashMap implementation in Rust nightly, some non-deterministic tests started failing. This is a quick PR to fix this. It also seems that there are changes to `cargo fmt` so there are formatting changes in this PR too.
I commented out `csv_query_group_by_avg_multi_batch` for now as there is something more complex causing that one to fail. I can look at that over the weekend.
Author: Andy Grove <an...@gmail.com>
Closes #4217 from andygrove/ARROW-5217 and squashes the following commits:
