## Current Behavior
`@nx/js:verdaccio` current call `npm config` to setup npm scopes in
global `.npmrc` file, which it's supposed to do.

However, when process is killed (using terminal exit command or any
other way), the process is killed and doesn't restore changed config.

In my case I'm changing scope to my private scope (using `scopes`
option), but after kill I need to restore manually.

## Expected Behavior
When process be killed, restore all configs that was set.
