Looks like second replicator not working after the start

Unit tests: 
-[DatabaseTest testDeleteWithActiveLiveQueriesAndReplicators]
-[DatabaseTest testDeleteWithActiveReplicators]
-[DatabaseTest testCloseWithActiveReplicators]
 

Steps:
1. Create two live queries
2. Create two replicators
3. Once the replicators are idle,
4. Delete/Close the database, which should ideally stop replicators and live queries.
5. Somehow the one replicator is hang
6. One thing which is uncommon is, we are using two replicators which have same config(pushAndPull) on same DB, which is not a usual.
