  - Don't reset storage when rescheduling for collisions
    
    When rescheduling to avoid a collision with an already inflight push, do
    not reset the persistent storage as this was not started to begin with
    as the "runway" was denied. This avoids extra bogus FileNotFound log
    messages.
