[code] smooth VS Code desktop flow

[akosyakov]

What it does

fix #4780

Changes in Gitpod Code: gitpod-io/openvscode-server@b1465c2

How to test

• Go to preferences and enable latest VS Code: https://ak-vscode-desktop.staging.gitpod-dev.com/preferences
• Start a workspace: https://ak-vscode-desktop.staging.gitpod-dev.com/#github.com/akosyakov/parcel-demo
• File -> Open in VS Code
• First time it will ask you to install Gitpod extension, you will also go through the auth flow, and eventually see the remote ssh window for Gitpod workspace.
• Try to close and open again, second time the flow should be smoother.

Works really well. The only thing I noticed was that the terminals didn't open as in the web version (I was using insider).
