Trying to install crow locally with npm install results in errors:

This looks similar to #163 and may be caused by some npm install <package> --force that break the dependency tree. Maybe we should start from a empty package-lock.json and see if we can build a clean dependency tree.

In addition to fixing this, we could try to update some dependencies.

@niconoe any insight into this would be highly appreciated. 😄

Steps taken:

1. Remove package-lock.json
2. Remove node_modules
3. Run npm cache clean --force
4. Run npm install

This works and indicates:

added 2510 packages, and audited 2511 packages in 2m

169 packages are looking for funding
  run `npm fund` for details

47 vulnerabilities (1 low, 10 moderate, 31 high, 5 critical)

To address issues that do not require attention, run:
  npm audit fix

To address all issues (including breaking changes), run:
  npm audit fix --force

Run `npm audit` for details.

But this breaks npm run serve and npm run test:unit

Fixed in #187
