npm scripts are failing

[umesh-timalsina]

npm start fails with the following error message

Error: Cannot find module 'deepforge-dev/deepforge/bin/start-worker.js'
    at Function.Module._resolveFilename (internal/modules/cjs/loader.js:797:15)
    at Function.Module._load (internal/modules/cjs/loader.js:690:27)
    at Function.Module.runMain (could beinternal/modules/cjs/loader.js:1047:10)
    at internal/main/run_main_module.js:17:11 {
  code: 'MODULE_NOT_FOUND',
  requireStack: []
}

It is because of https://github.com/deepforge-dev/deepforge/blob/master/package.json#L17
and function startLocal not being update for updated worker logic in #1600
