workspace never comes up when Che deployed with single-host strategy

Describe the bug

Che workspace never comes up when Che deployed with single-host strategy

Che version

• latest

Expected behavior

Runtime

• minikube (include output of minikube version and kubectl version)

Screenshots

Installation method

Actually chectl doesn’t support changing server strategy. That’s why I modified sources https://github.com/che-incubator/chectl/blob/master/src/tasks/installers/helm.ts#L349 by adding setOptions.push('--set global.serverStrategy=single-host')

• chectl ./run server:start --platform=minikube --installer=operator --che-operator-cr-patch-yaml <patch_yaml>

spec:
  k8s:
    ingressStrategy: single-host

Environment

• my computer
  • Linux

I think I found and fixed the issue. https://github.com/eclipse/che-theia/blob/master/extensions/eclipse-che-theia-messaging/src/node/messaging/che-messaging-contribution.ts#L81

The objects here looks like this:

2020-07-22 12:40:22.990 root INFO theiaEndpoints: [{"codeUri":{"$mid":1,"path":"/server0lrge5i9-theia-idexh4/server-3130/","scheme":"https","authority":"che.192.168.39.154.nip.io"}},{"codeUri":{"$mid":1,"path":"/serverz6bqowu3-jwtproxy/server-4402/","scheme":"https","authority":"che.192.168.39.154.nip.io"}}] 
2020-07-22 12:40:22.990 root INFO requestOriginURI: {"codeUri":{"$mid":1,"path":"/","scheme":"https","authority":"che.192.168.39.154.nip.io"}}

isEqualOrParent function looks like this (https://github.com/eclipse-theia/theia/blob/14531578a1eac6af55c6177ea857d39c38c9f09b/packages/core/src/common/uri.ts#L202):

isEqualOrParent(uri: URI): boolean {
  return this.authority === uri.authority && this.scheme === uri.scheme && this.path.isEqualOrParent(uri.path);
}

issue is in this.path.isEqualOrParent(uri.path) where we are comparing them in reverse. Swapping them fixes the issue.
