When in a source directory, I expect cargo uninstall to remove the compiled package from ~/.cargo/bin. It doesn't seem to do so.

In this example I start with no uutils, cargo install, have uutils, cargo uninstall, still have uutils:

brian@DESKTOP-UCV672I:~/coreutils⟫ ls ~/.cargo/bin
basic-http-server  cargo-benchcmp  cargo-fuzz      cargo-upgrade  mdbook  rustc    rustfmt-format-diff  rustup  wasm2es6js                wasm-pack
cargo              cargo-clippy    cargo-generate  comrak         rg      rustdoc  rust-gdb             tokei   wasm-bindgen
cargo-add          cargo-fmt       cargo-rm        git-fmt        rls     rustfmt  rust-lldb            twiggy  wasm-bindgen-test-runner
brian@DESKTOP-UCV672I:~/coreutils⟫ cargo +nightly install

Tested on stable and nightly.
