chore: bump various dependencies

- grunt -> 1
- grunt-contrib-watch -> 1
- mocha -> 5
  - in common.js: define "global" , see mochajs/mocha#1159
  - in builtins.js: revert "console.log" to old value just
    after using the mock (in log-helper tests), because
    mocha calls "console.log" on failure, before
    "afterEach"
