Environment data

VS Code version: 1.19.0
Python Extension version: 0.9.0
Python Version: 3.7.14 x64
OS and version: Windows 10 Pro 1709

Actual behavior

When saving a .py file VSCode/Python Extension keeps saying "Error Linter Pylint is not installed".
Selecting "Install Pylint" again only shows that it is already up to date.
While I can select "Don't show this prompt again" selecting that does not feel good because then it will probably not show up again at all (even when needed).

Expected behavior

Speaks for itself: Only show error and options if true.

Steps to reproduce:

• Install VSCode 1.19.0 on Windows
• Install Python v2.7.14 x64
• Install VSCode Python Extension v0.9.0
• Open some python (.py) file, edit and save.
