Sometimes, wrong packages are linked

[yeegor]

Describe the bug

The current package linking flow is as follows:

1. go to the linkable package
2. run npm link
3. go to the target package
4. run npm link <linkable package **name**>

This flow breaks on step 2 when a package with such a name already is linked. It does not get overwritten, and hence in step 4 - the old package gets linked. A possible solution for this would be to unlink the package before linking it again.

Steps to reproduce

(Write your steps here:)

1. Have a CSA project with a local package named X
2. Outside of that project, create another (different!) package with name X, run npm link on that
3. Run dep linking in your project

Expected behavior

The package from step 1 is linked

Actual behavior

The package from step 2 is linked
