  - Avoid checking for existing tasks while pruning
    
    When the distributor runs, it now stores a snapshot of pending
    pushes and then removes from this snapshot all the RefUpdates
    which were found while adding pending persisted tasks. The
    remaining pushes in the snapshot can now be pruned without
    needing to do an existence check on them since they were no
    longer stored persistently (and thus no longer needed to be
    executed). This effectively makes pruning I/O less, thereby
    reducing the load put by distributor on disk I/O.

  - Add a test to cover Distributor pruning feature
    
    To test if distributor can prune, we add an event to storage and
    then delete the waiting task from storage to simulate it being
    started by another node. We then assert that the project task
    gets pruned from the work queue by the time the next distribution
    cycle completes.
