refactor(plugin-js-packages): provide package json path + e2e test

[vmasek]

• option to provide package.json path
• remove confusing parameter of packageJsonPahts that was used just to count outdated deps
• create e2e tests
• fallback from current to wanted (current is missing if node_modules folder does not exist and we audit just using package log)
