fix(cache): add both full and minified packument to cache (#7516)

This will fix the `npm cache add` to cache package with same header as
it's used in `npm install` by adding extra manifest call with
`fullMetadata: true` while caching to match behaviour with install
command which internally request manifest with fullMetadata.
