[Bug] yarn up does not properly update non-npm dependencies

[andreialecu]

• I'd be willing to implement a fix

Describe the bug

Running yarn up pkg where pkg is a git dependency removes the git dependency and replaces it with a npm dependency.

To Reproduce

Reproduction

await yarn('init', '-y');
await yarn('add', 'left-pad@left-pad/left-pad');
await yarn('up', 'left-pad')

expect(require("./package.json").dependencies["left-pad"]).toEqual("left-pad/left-pad")

[andreialecu]

This is particularly dangerous if a dependency's name is something common (eg. utils) and unrelated to the utils on npm .

I think the expected behavior or yarn up pkg would be to refresh pkg to the latest commit available without changing its resolution.

Low risk, but in theory, a malicious package could be created on npm to target some internal package used at some company, and run some install script once someone runs yarn up project1-utils. (think previous employee with knowledge of internal package names, etc)

This issue reproduces on master:

Error: expect(received).toEqual(expected) // deep equality

I'm also getting an error [YN0027] when trying to update a private package using a git+ssh url. But when I put the entire package-name@remote-url like I did in yarn add, it updates just fine. I tought he used the same package name to resolve the url in my package.json. Am I missing something?
