Fix package-lock.json and update lodash to 4.17.15

This CL removes a duplicate "}," line in package-lock.json, making it
possibly to run `npm install` again. This line was probably introduced
by a bad merge.

This also updates lodash to 4.17.15 as recommended by `npm audit`,
addressing the vulnerability https://nodesecurity.io/advisories/1065.

The audit also reveals https://nodesecurity.io/advisories/813, a
vulnerability in js-yaml used by mocha. This CL does not address this
because it would mean going from major version 5 to 7 of mocha, and
mocha is not affected by this vulnerability since it uses safeLoad
(https://github.com/mochajs/mocha/issues/3880#issuecomment-484794696).
