Pull replication does not work - getActiveReplicators() list still populated

[Che Jami]

This used to work fine but one or two commits (all the way to latest) after d6be09b results in a break in our pull replication, both authenticated and not authenticated.

No data is pulled and there is no further activity after this, however we use a background thread that continuously queries getActiveReplicators() on the database to figure out when a sync has completed (we only do pull replications).

In this case the active replicators list is always populated after this.

We need a test that somehow when replication are dropped (maybe by the server) that this API correctly lists their status.
