Notify the SubscriptionController that a connection closed from the
Connection instead of having the subscription controller set up an event
to do so. This simplifies the logic on the SubscriptionController's
side.
Entites that didn't have an updatedAt time at the time of creation will
default to having one set to 0. Since entities with an updatedAt time
greater than lastResponseTime is expected to be returned this means that
these entities would not be included when a client does its initial sync
subscribing to a resource. Change the default lastResponseTime
requested so that these entities are included.
