Fix CI

- Fix clippy warnings
- Fix MSRV task to use latest stable to install `cargo-sweep`

  Before, it would use the lower version to install, which broke when cargo-sweep updated its own MSRV.

- Fix tests not to conflict with one another

  They were using the same target directory, which caused them to fail for some reason.
  I expect this is related to rust-lang/cargo#8640 somehow but it doesn't seem worth investigating.
