tests fail to build - possibly due to package-lock.json absence

[Rogach]

Describe the bug

package-lock.json is not commited into the repo, and it seems it leads to some differences between installations that make tests fail (see below).

Reproducing

$ git clone https://github.com/zeromq/zeromq.js.git
$ cd zeromq.js
$ npm install
$ npm run test

> [email protected] test
> npm run build.js && mocha

> [email protected] build.js
> tsc --project tsconfig-build.json && node script/ci/downlevel-dts.js

Found 3 errors.

Expected behavior When running npm install dependencies are exactly equal to the ones used in other developer's environments and thus tests build and execute successfully.
