    13649: Fixes default preemptible parameter when submitting committed child CRs
    
    Two problems fixed:
    1) When submitting a committed child CR, its preemptible parameter is set.
    2) Resolve a container for said child CR after the preemptible parameter setting.
    
    Added tests for committed child CR submissions.
