What this does

Yarn 2 resolutions breaks snyk test. See https://github.com/snyk/nodejs-lockfile-parser/issues/99 for details. This PR unblocks consumers that have yarn 2 resolutions when --strict-out-of-sync=false is passed to the Snyk CLI.

Notes for the reviewer

See additional test case for yarn 1 and yarn 2` resolutions.

Hey @mhassan1 We have been looking into getting this contribution merged and have merged these commits into another PR (https://github.com/snyk/nodejs-lockfile-parser/pull/102) to squash the commits and get the checks to pass. Interestingly once the checks passed on the PR, they passed over here too.

We are going to merge your commits into master from the other PR and close this as that is our current process.

Thanks for your contribution 😀
