v7.0.1 leaves processes hanging on Windows

[XhmikosR]

• cross-env version: 7.0.1
• node version: 12.16.1
• npm version: 6.13.4

What you did:

npm run make-fake-data && cross-env REACT_APP_FAKE_API=1 npm run start

What happened:

Reproduction instructions:

Assuming you are on Windows:

git clone https://github.com/pi-hole/web -b development
npm i && npm run start-fake

Then try to ctrl+c the process. One needs to hit ctrl+C twice. If you don't do it twice, then you can check the task manager and you will see node.exe left running

Initially reported in the PR that introduced the issue here. Going back to v7.0.0 works as expected.
