Temporary files created by CLI are not deleted in some cases

[rosen-vladimirov]

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: 6.3.3
• Cross-platform modules: Not applicable
• Android Runtime: Not applicable
• iOS Runtime: Not applicable
• Plugin(s): Not applicable

Describe the bug
During some of the CLI operations, temporary files are created. In case CLI's process is killed (via Ctrl+C or some other way), the temporary files remain in the temp directories.

To Reproduce

tns create myApp --js
cd myApp
tns prepare android --log trace
Ctrl + C once the webpack build starts

Now check the logs for message in format:

Calling pacoteService.extractPackage for packageName: 'tns-android@6.3.1', destinationDir: 'C:\Users\VLADIM~1\AppData\Local\Temp\runtimeDir12014-5172-11uveur.rfos' and options: undefined

Check the mentioned location and you'll see it still exist, even when you've killed the CLI process.

Expected behavior
All temp files must be deleted.
