Respect app_provider values from capabilities

[michaelstingl]

@DeepDiver1975 reported in https://github.com/owncloud/enterprise/issues/5747#issuecomment-1593139899, Android app doesn't respect the app_provider values from the capabilities

      "capabilities": {
        "files": {
          "app_providers": [
            {
              "enabled": true,
              "version": "1.1.0",
              "apps_url": "/app/list",
              "open_url": "/app/open",
              "open_web_url": "/app/open-with-web",
              "new_url": "/app/new"
            }
          ]
        }
      }

Specifically: apps_url is not respected in my test. No matter what the server (owncloud 10) is returning as path - android app is still calling /app/list
