Problem
when running cargo update in the rustc or rls repo, it looks like the clippy repo inside the cache is updated twice. This seems redundant.

  Updating crates.io index
    Updating git repository `https://github.com/rust-lang/cargo`
    Updating git repository `https://github.com/rust-lang/rust-clippy`
    Updating git repository `https://github.com/rust-lang/rust-clippy`
      Adding addr2line v0.12.1
    Updating anyhow v1.0.28 -> v1.0.31

Steps

1. cargo update

Possible Solution(s)
Don't update the git repo two times back-to-back.

Notes

Output of cargo version:
cargo 1.45.0-nightly (cb06cb269 2020-05-08)

Note: It doesn't look like cargo update -vvvvv has any additional effect :/
