Disable IDEA automatically creates Grails run configurations from detected plugins

What steps will reproduce the problem?
1. Load a Grails project without run configurations
2. IDEA creates run configurations

What is the expected result?
I should be able to disable this feature.

What happens instead?
I cannot disable this.

Automatically detecting and creating run configurations was introduced a year or so ago it seems. This is creating superfluous run configurations from detected Grails plugins that exist in my project but I do not want to have a run configuration associated with. This happens at restart every time.

Start by reproducing the issue with a Grails project that has no run configurations, then trace the plugin entry point that detects Grails plugins and creates configurations. Done means users can disable that automatic creation and the unwanted configurations are not recreated when the project restarts.
