'Failed to load plugin 'self' declared in '--config': enabledPluginName.replace is not a function' with v9 compatible add-on

[Standard8]

When attempting to use this plugin with a v9 compatible add-on, a message such as this is produced:

TypeError: Failed to load plugin 'self' declared in '--config': enabledPluginName.replace is not a function

The new configuration format allows for a combination of:

{
  "configs": {
    "recommended-legacy": {
      "plugins": ["json"],
      "rules": {
        "json/*": "error",
      },
    },
    "recommended": {
      "plugins": { // object that refers to the plugin itself }
      "rules": {
        "json/*": "error",
      },
    }
  }

so this needs to be handled in some manner.
