plone.staticresources release contains multiple package.json files that are picked up by Jest

[tisto]

When running Jest (JS test runner) tests on a code-base with Plone, it picks up plone.staticresource files automatically:

    The name `react` was looked up in the Haste module map. It cannot be resolved, because there exists several different files, or packages, that provide a module for that particular name and platform. The platform is generic (no extension). You must delete or blacklist files until there remains only one of these:
      * `/home/iflameing/Documents/github/volto/api/eggs/plone.staticresources-1.2.1-py3.6.egg/plone/staticresources/static/components/react/npm-react/package.json` (package)
      * `/home/iflameing/Documents/github/volto/api/eggs/plone.staticresources-1.2.1-py3.6.egg/plone/staticresources/static/components/react/src/package.json` (package)

Is it possible to exclude package.json files from the releases via MANIFEST.in. IMHO those files do not belong into a release. Though, TBH I have no idea what plone.staticresources does or how it works. :/

@tisto how about to proceed with the blacklist option?

looks like the docs changed; the option would be probably: https://jestjs.io/docs/en/configuration.html#testpathignorepatterns-arraystring

We need to add "package.json" to https://github.com/plone/plone.staticresources/blob/master/src/plone/staticresources/static/.gitignore and remove all package.json files from the https://github.com/plone/plone.staticresources/tree/master/src/plone/staticresources/static/components folder.
