Current behavior

nest start always start in debug mode due to unsafe checks
Options contain even not initialized values:

[
  { name: 'config', value: undefined },
  { name: 'webpack', value: undefined },
  { name: 'debug', value: undefined },
  { name: 'watch', value: false },
  { name: 'watchAssets', value: false },
  { name: 'path', value: undefined },
  { name: 'webpackPath', value: undefined },
  { name: 'exec', value: undefined },
  { name: 'preserveWatchOutput', value: false }
]

So next check is false-positive

nest-cli/actions/start.action.ts

Line 140 in c745366

if (debug) {

also, this one is suspicious

nest-cli/actions/start.action.ts

Line 62 in c745366

!!debugModeOption,

Expected behavior

--debug or --debug-brk options control that

Minimal reproduction of the problem with instructions

Seems to be broken in #592

Simply make npm i in https://github.com/nestjs/nest/tree/master/sample/12-graphql-schema-first or any other sample

➜  12-graphql-schema-first git:(master) ✗ ./node_modules/.bin/nest start
Debugger listening on ws://127.0.0.1:9229/c822fd22-351f-425b-b25a-cf354383e901

What is the motivation / use case for changing the behavior?

@kamilmysliwiec, I'm looking into this and trying to fix my bug, but I am a bit confused. Even if I do nest start --debug, options still looks like this:

  { name: 'config', value: undefined },
  { name: 'webpack', value: undefined },
  { name: 'debug', value: undefined },
  { name: 'watch', value: false },
  { name: 'watchAssets', value: false },
  { name: 'path', value: undefined },
  { name: 'webpackPath', value: undefined },
  { name: 'exec', value: undefined },
  { name: 'preserveWatchOutput', value: false }
]

How does it work?
