Environment data

VS Code version: 1.19.0
Python Extension version: 0.9.0
Python Version: 3.5.2
OS and version: Ubuntu 16.04 64bit

Actual behavior

os.environ['PATH'] will raise KeyError(key) when running a program using Ctrl+F5 or only F5.
But everything is fine when running the program in the console.

Expected behavior

os.environ['PATH'] should get the environment variable PATH.

Steps to reproduce:

• Update Python Extension to version 0.9.0
• Run a program with code "import os; print(os.environ['PATH'])" using Ctrl+F5 or only F5
