nodeJS processes not killed after 'tns create' on Mac OS with latest "next"

[VladimirAmiorkov]

Environment
Provide version numbers for the following components (information can be retrieved by running tns info in your project folder or by inspecting the package.json of the project):

• CLI: 5.4.0-2019-05-08-13226
• Mac OS version: 10.14.4 (18E226)

Describe the bug
When creating a project using tns create testapp --js, after the creation is finished if you open Activity Monitor and search for "node" you can find at least 2 processes left.

To Reproduce

• Install the 5.4.0-2019-05-08-13226 version of the CLI npm i nativescript@5.4.0-2019-05-08-13226
• Open Activity Monitor
• Do tns create my-app --js
• Search for "node" in the Activity Monitor

Expected behavior
After creation of the project there are no nodeJS processes left alive.

Another way to check if there are leaked processes is by using the following command (after CLI has died):

ps -ef | grep nativescript | grep -v grep
