Brief summary of the bug. What is it ? Where is it ?

When using Optimize in cloud mode, the frontend calls the "ui-configuration" endpoint. Part of the response to that call contains wrong/useless information from C7 Mode:

"webappsEndpoints" : {
    "camunda-bpm" : {
      "endpoint" : "http://localhost:8080/camunda",
      "engineName" : "default"
    }
  } 

This shouldn't be in the response if running in C8 mode.

Steps to reproduce:

Open Optimize in C8 mode, run developer tools in your browser (F12) and read the response from "ui-configuration"

Actual result:

The code above is part of the response

Expected result:

The code above should not be there
