Small improvements to wrangler init

• TypeScript configuration seems to be slightly incorrect:
  • src/index.ts: Cannot find name Promise
  • tsconfig.json: Cannot find global type Array
• scripts in package.json should be prepopulated with some defaults, e.g.

"scripts": {
  "start": "wrangler dev src/index.ts",
  "deploy": "wrangler publish src/index.ts" 
}

• wrangler.toml is only populated with compatibility_date, but should also contain:
  • name, matching the name of its directory.
  • workers_dev = true, so it’s easy to publish.

I’m not aware of whether that fixed the Promise/Array issue. But also, that bug looks highly suspicious, it shouldn’t really occur. Might’ve just needed a vscode restart. If you’re not able to reproduce that issue, consider it fixed.

To clarify, we’re deprecating the workers_dev field altogether in wrangler 2, its value can be inferred by the presence/lack of routes. (Unless I’m missing some usecase)

Right… forgot about that. So only the name would be good to add.
