Watch doesn`t work correctly with links

Do you want to request a feature or report a bug? Bug report.

What is the current behavior? When i create link in node_modules and set symlinks to false, I have problem with watch, it works sometimes (more often it doesn`t work)

If the current behavior is a bug, please provide the steps to reproduce.

1. create link
2. set symlinks to false
3. change file by link

What is the expected behavior? Watch must work

If this is a feature request, what is motivation or use case for changing the behavior?

Please mention other relevant information such as the browser version, Node.js version, webpack version and Operating System.

This issue was moved from webpack/webpack#6122 by @sokra. Orginal issue was by @arshtepe.

@evilebottnawi I have created repo https://bitbucket.org/CyBer_UA/webpack-demo/src/344771d7d4b403eb662a9c0e7f23aaedc920f0e9?at=master To reproduce you need:

cd repo/
npm link
cd ..
npm link simple-repo
webpack --watch

and after that you need to change file index.js in repo folder from

import test from "src/test";

to

import test from "./src/test"; 

and after webpack do nothing…

I believe the solution here is to set chokidar.followSymlinks to true if webpack’s resolve.symlinks is set to false: https://github.com/webpack/watchpack/blob/master/lib/DirectoryWatcher.js#L54

@evilebottnawi The PR is at https://github.com/webpack/watchpack/pull/72, I believe.
