Upgrade confused by multiple instances of the same package, writes invalid config

[awused]

I have a project that depends on both image git and image v23 for compatibility with other crates.

[dependencies]
image_23 = { package = "image", version = "0.23.14" }
image = { git = "https://github.com/image-rs/image" }

cargo upgrade --dry-run showed no changes related to image, but running cargo upgrade changed the config to:

[dependencies]
image_23 = { package = "image", version = "0.23.14" }
image = { version = "0.23.14", package = "image" }

After the upgrade the config was invalid since it was depending on image v23 twice under different names.

Duplicate of #432.

I'm not sure this is a simple dupe, or if it is it's a different symptom, because this one is downgrading a manually set git dependency to an earlier published version.

This is resolved now at least after #725
