Remove racy portion of rspec test

We can't assume bandersnatch hasn't run yet after puppet is done since
it runs on a cron it could start running even while puppet is still
running. Instead just assert that it does its job after it should have
run. This fixes a test failure due to the racyness that existed
previously.
