cargo add crate-name & cargo add crate_name have different results when crate_name is already present

[GrigorenkoPV]

Problem

Example manifest:

[package]
name = "add"
version = "0.0.0"

[dependencies.derive_more]
version = "0.99"
default-features = false
features = ["display"]

Steps

cargo add derive_more changes nothing.
cargo add derive-more resets chosen features and sets the version to latest available.
