Theia doesn't update command's previewUrl on 2nd workspace start

Describe the bug

When workspace is started 2nd time, commands attributes are not updated. This happens for previewUrl. Preview url is dynamic attribute. It is different at each workspace startup, because randomly named kubernetes services/ingresses are created for it. Theia probably caches some values, which is problem here.

From attached screenshot you can see that in response for workspace, previewUrl is different than the one that Theia tries to open.

Che version

• other: please specify PreviewUrl in devfile is not merged yet. It is implemented in this task https://github.com/eclipse/che/issues/13945 and PR is currently open https://github.com/eclipse/che/pull/14713 I’ve prepared test server image quay.io/mvala/che-server:previewurl

Steps to reproduce

1. Start workspace with command that has previewurl
2. Stop the workspace
3. Start the workspace again
4. Run the command with previewurl
5. Opened url does not exists because the ingress host is different

Expected behavior

Commands should be updated with values received from the server.

@l0rd I need to verify that with @RomanNikitenko. This might still be an issue.

we’ve implemented previewUrl with variables so we don’t need to refresh tasks.json at each workspace startup. tasks.json <> devfile synchronization issue is here https://github.com/eclipse/che/issues/13994. Closing this one
