    Pre-load group for PixelDataThread.makeEvent (Fix #9223)
    
    Use of "omero.group"=="-1" during writing threads will
    often lead to the error "Not intended for copying".
    
    Here, we pre-load the group that we are looking for by
    using "-1", and then set the group explicitly to that
    value.
