  - ReplicationIT: fix flakiness
    
    Fix the flakiness when checking for replication tasks stored
    events on the filesystem and when replicating new projects.
    
    Make use of the ReplicationTasksStorage for listing events
    instead of listing the filesystem and allow disabling the deletion
    so that the tests can have the time to verify the files existence.

  - ReplicationIT: Split waitUntil to a separate class and fix it
    
    The waitUntil method does not fail the test if the expected condition
    is not satisfied within the timeout; it just returns.
    
    Split it out to a separate class, to make it easier to test, fix
    it, and add tests.
