fix nodeterministically failing test in the host

The test was to make sure a probabilistic action was occuring a
reasonable number of times, but was only performing 10 actions to
measure a rare event. To fix the  test, the number of actions was
increased from 10 to 100, smoothing out the fluctuations in the
randomness.
