Adds scrypt support in node 12 (#739)

* Adds scrypt support in node 12

Replaces scrypt npm module (no longer maintained and
doesn't work for node 12) for testing standard scrypt with
`crypto.scryptSync` which has been supported since node v10.5.

* Fixes http timeout issues in node 12.

* Updated CI config; Re-generated the package lock file
