symlink tests fail when you run tests on Windows.

🐛 bug report

When you run tests on Windows, tests that use symlinks fail because Windows doesn't allow symlink to normal users by default for security. (You need admin privilege to run them.)

Note: It's the issue for #2590. I'm writing it here because I messed that PR up and started again from scratch.

I'll publish new PR soon.

🎛 Configuration (.babelrc, package.json, cli command)

None

🤔 Expected Behavior

Tests pass without any problem.

😯 Current Behavior

Tests fail and show EPERM error message like below:

 1) resolver
       "before all" hook:
     Error: EPERM: operation not permitted, symlink 'D:\parcel\packages\core\parcel-bundler\test\input\resolver\packages\source' -> 'D:\parcel\packages\core\parcel-bundler\test\input\resolver\node_modules\source'
      at symlinkSync (fs.js:905:3)
      at Context.<anonymous> (test\resolver.js:18:5)
      at process._tickCallback (internal/process/next_tick.js:68:7)

💁 Possible Solution

Open cmd or powershell with admin privilege. If you're not sure, check this post.

🔦 Context

I wanted to contribute to Parcel. So, I forked and cloned the repo and ran test. But it failed without admin privilege warning.

I think it's bad for new contributors like me.

💻 Code Sample

None.

🌍 Your Environment

Software	Version(s)
Parcel	1.11.0
Node	10.15.0
npm/Yarn	1.12.3
Operating System	Windows 10 Pro 1803

This should work if you run it as administrator for some reason symlinks in windows require high privileges
