Running `code` command early - results in an error

Bug description

Running code README.md early - results in an error

.gitpod.yml

tasks:
  - command: |
      code README.md

HISTFILE=/workspace/.gitpod/cmd-0 history -r; {
> code README.md
> 
> }
Unable to connect to VS Code server: Error in request.
Error: connect ECONNREFUSED 127.0.0.1:23000
    at TCPConnectWrap.afterConnect [as oncomplete] (net.js:1146:16) {
  errno: -111,
  code: 'ECONNREFUSED',
  syscall: 'connect',
  address: '127.0.0.1',
  port: 23000
}

Steps to reproduce

Open the example repo in Gitpod -
https://gitpod.io/#https://github.com/shaal/gitpod-test--port-23000
You'll see the error about port 23000

vs.

The same repo, but in a branch that adds sleep 10:
https://gitpod.io/#https://github.com/shaal/gitpod-test--port-23000/tree/sleep-10-seconds

Workspace affected

No response

Expected behavior

Commands should run flawlessly.

Example repository

https://github.com/shaal/gitpod-test--port-23000

Anything else?

This bug seems to be worse on slower machines (and perhaps slower internet?)

Start by reproducing the issue from the example repository and compare the .gitpod.yml task that runs code README.md with the branch that adds sleep 10. Trace the startup path for the VS Code server and the code command around port 23000; done means the command succeeds without requiring a manual delay, including on slower machines.
