ApiCoreThankIntegrationTest: Fix intermittent failures

Browse source 
Every time the setup function runs, it chooses a random page name with
random content. If it chooses a page name + content combination that was
used to set up a different test in the same run, the edit it makes will
be a null edit, the revid will be null, and the test will crash.

There are 100 possible page names and 100 possible page texts, so 10k
possibilities total, and the setup function appears to be called 10 times,
so the probability of a collision would have been
(10 choose 2)/10000 = 0.0045 = 0.45%, or one in every 222 times.
