Description of problem:
This is a follow-up on OCPBUGS-14964. The Alertmanager page doesn't work when the monitoring-plugin (tested with version 1.0.0) is enabled.

Version-Release number of selected component (if applicable):
4.14.0 nightly

How reproducible:
Always on a nightly 4.14 cluster with enabled monitoring-operator

Steps to Reproduce:
Navigate to Cluster Settings > Configuration > AlertManager

Actual results:
The page shows just an empty page. No loading indicator, no content.

Expected results:
Page should load as there is no monitoring-plugin

Additional info:
The monitoring-plugin says its responsible for all /monitoring/ URLs

    {
      "type": "console.page/route",
      "properties": {
        "exact": false,
        "path": "/monitoring/",
        "component": {
          "$codeRef": "MonitoringUI"
        }
      }
    },

But some the paths /monitoring/alertmanageryaml and /monitoring/alertmanagerconfig are handled by the console itself.
