Client is prompted "Do you want to save changes" when closing VS Code with dirty files

[DanTup]

I started a live session and joined it from another VS Code instance. Then I made some changes on the host (both host and client got dirty file indicators). I tried to close the Client VS Code and it prompted me to Save/Don't Save changes.

Clicking "Don't Save" sounds like your file will be reverted, but of course it's not - it stays open and modified on the host.

What was your system configuration? Product and Version [VS/VSCode]: 1.44.2 OS Version[macOS/Windows]: macOS Catalina Live Share Extension Version: 1.0.2000 Target Platform or Language [e.g. Node.js]: Dart

Steps to Reproduce / Scenario:

1. Share a live session
2. Modify file (but don't save) in host
3. Close client VS Code
4. See prompt
