camel-health - Route health check with consumer should be DOWN until first poll executed

When using health check then you can have a situation where a route is UP during startup, because the route is started, but the scheduled consumer has not executed a poll yet.

And if that poll then fails, then the status can be DOWN due to the error.

So you can have UP -> DOWN that goes quickly.

Instead we should keep it as DOWN until at least one poll has been executed so we know if that is a success or not.
