[MS Language Server] Go to definition cannot traverse workspaces

[amittleider]

Currently the MS Language Server won't allow jumping to a class (using Go to Definition) if it's found in a different VSCode workspace.

Environment data

• VS Code version: 1.35.0
• Extension version (available under the Extensions sidebar): 2019.5.18875
• OS and version: Ubuntu 18.04
• Python version (& distribution if applicable, e.g. Anaconda): 3.6.7 64 bit
• Type of virtual environment used (N/A | venv | virtualenv | conda | ...): venv
• Language Server (more info How to update the language server to the latest stable version #3977): LS

Expected behaviour

Go to definition jumps to the Level1Class object

Actual behaviour

Definition not found. Below is a gif.

Steps to reproduce:

• Use this repo: https://github.com/amittleider/vscode_multi_workspace_bug_repro
• Go to the file upper_level_class.py
• Try to jump to the definition of the Level1Class object.
• It will probably say "Cannot find definition"
