Fix bug with defining connect healthcheck

Previously we were setting the alias_service field of alias checks to
the service name instead of the service id. This check would then pass
because Consul would consider an alias for a non-existent service id to
be okay. With hashicorp/consul#7384, now the
check will fail if the service id doesn't exist and so those connect
services will be considered unhealthy and be unroutable.
