  - Make the shouldReplicateNewProject test more reliable
    
    The ReplicationIT shouldReplicateNewProject was failing regularly on my
    machine. Improve the timeout for this test so that it explicitly
    includes the time needed to wait for the project to be created, not just
    the scheduling and retry times.
