Describe the bug

Workspace URL is redirected to dashboard.

Che version

next (development version)

Steps to reproduce

1. Deploy Che on minikube with next chectl:

chectl server:deploy --installer=operator --platform=minikube --che-operator-cr-patch-yaml=/home/sleshche/che-custom-che-server.yaml --workspace-engine=dev-workspace

where patch file has the following content

spec:
  devWorkspace:
    enable: true
  server:
    customCheProperties:
      CHE_INFRA_KUBERNETES_ENABLE__UNSUPPORTED__K8S: "true"

2. When Dashboard is opened, create a workspace with Sample and wait it started.

3. Check that Dashboard is opened instead of Theia IDE.

4. Switch single host impl to gateway by adding spec.k8s.singleHostExposureType: gateway into Che Cluster, wait Che is reconfigured.

5. Try a new workspace or restart the existing one.

6. Check that Theia is not opened.

Expected behavior

Theia is opened after workspace is started.
