    tests: fix potential divide by zero condition
    
    Running clang's static analysis revealed a possible divide by zero
    condition.
    
    There is a random chance of the divide by zero.
    
    - it has to be in the first pass of the main loop testing events
      (counter = 0)
    - 90% chance path :   if (counter < (NUMEVENTS -1) &&
                              random() % 10 == 0)      -- needs to be false
    - 25% chance path:    if (random() % 4 == 0)       -- needs to be true
    
    if the above conditions are met, the statement
        int victim = random() % counter
    is a divide by zero.
    
    Add a check to ensure the counter is greater than zero.  Add a comment
    to document that only events prior to the current event are randomly
    selected.
