* Apply 'no-unnecessary-initializer' lint rule Forbids `let`/`const` statements to be initialized to `undefined`, since that's the initial value by default anyway. The auto-fixer also happened to remove two unnecessary `as number` casts in `src/harness/parallel/worker.ts`. For historical data: to run with `--fix`, I modified the line in `Jakefile.js` that declared the `cmd` for running TSLint. * Moved worker.ts type assertions to parameters
