This adds additional state guardsof the idle_status method, which will
prevent it from being run until a worker has joined the relationship.
Previous invocations may have some message artifacting, but will reach
eventual consistency once a worker has joined.
This prevents the polling loop from executing too soon, bloating the
installation time by bare-minimum an additional 10 minutes.
