This fixes a regression where dependencies would only be started in
order and would start the dependent service if its dependency had been
started at some point in the past, regardless of the running condition.
This makes the behavior more consistent with docker compose where the
[dependency needs to be
running or healthy](69a83d1303/pkg/compose/convergence.go (L441)) for the service to be started.
