Component is added as a dependency upon import even when using --ignore-package-json flag

[davidfirst]

Describe the bug

When importing a component with --ignore-package-json flag, the component's root dir, doesn't have the package.json file, so there is no point of adding that component with the relative-path into the workspace's package.json file.

Steps to Reproduce

1. import a component with --ignore-package-json flag.
2. run npm install twice.
3. the following error is thrown

npm ERR! Cannot read property 'match' of undefined

Expected Behavior

No records should be added into root package.json when --ignore-package-json is used.
