Unable to delete listener with http enabled

I'm running into an issue when trying to delete a listener which has 'http: true' set. The router returns the error message "HTTP listeners cannot be deleted". I can see that there is a test for this in the router code as well.

However, in order for AMQ Online to be able to create and delete listeners that are used to handle websocket connections for different tenants, we need a way to delete listeners with http: true set without restarting the router.
