* Update lockfile to fix errors

npm has informed me that the lockfile has "errors":

    npm ERR! code ELOCKVERIFY
    npm ERR! Errors were found in your package-lock.json, run  npm install  to fix them.
    npm ERR!     Missing: c3@^0.6.7
    npm ERR!     Invalid: lock file's d3@3.5.17 does not satisfy d3@^5.7.0

* circleci: Disable npm audit when installing packages

Auditing packages when installing here doesn't help anyone as the summary
isn't visible and vulnerabilities don't produce a non-zero exit code. We
will have `npm audit` as an extra CI job.

* npm audit fix

* circleci: Replace nsp with npm audit

Refs #4751

* Remove beefy dependency and its usages

Refs #4768
Refs #5389

This changeset removes the beefy package that:

1. Was last published 2 yrs ago
2. Brought with it 1 moderate and 1 critical vulnerability
3. Was only used in scripts that no longer work

* npm uninstall open

* Update ganache-core to mitigate vuln

                       === npm audit security report ===

> # Run  npm install --save-dev ganache-core@2.3.1  to resolve 1 vulnerability

* Deduplicate package.json file

From `npm install`:

> npm WARN The package css-loader is included as both a dev and production dependency.
> npm WARN The package eslint-plugin-react is included as both a dev and production dependency.
> npm WARN The package file-loader is included as both a dev and production dependency.
> npm WARN The package gulp is included as both a dev and production dependency.

It's also worth noting that the Gulp version we were using was inconsistent and there is
a published v4 release on GitHub.
