vsc keeps installing pylint

[choeffer]

Environment data

• VS Code version: 1.33.1
• Extension version (available under the Extensions sidebar): 2019.4.12954
• OS and version: Debian Buster all updates applied
• Python version (& distribution if applicable, e.g. Anaconda): 3.7 from official Debian repositories
• Type of virtual environment used (N/A | venv | virtualenv | conda | ...): venv
• Relevant/affected Python packages and their versions: XXX

Expected behaviour

Just install pylint once in a new venv.

Actual behaviour

Vsc always tries to reinstall pylint even if it is already installed.

Steps to reproduce:

1. Set "python.pythonPath": in workspace settings.json, so that you use a venv which is not in the root of the workspace folder.
2. Open a Python file, modify it and save the changes. Every time you save the Python file, vsc will warn you and suggets to reinstall pylint, even if it is already successfully installed.

Also created one issue there microsoft/vscode#73665 , was not sure which is the proper place for this issue.

I can confirm this issue occurs but only when using a venv which is not in the root of the workspace folder.
