Since the test script was modified so that it doesn't create tidstore
before setting TIDs, the server crashed with SEGV. I remember that we
used to check that the tidstore is already created before use, but we
removed that check because it would not be very helpful; if a
developer wiped out the create call then the test crashes pretty
obviously[1]. Do we want to revive that check as raising an error is
better than a SEGV?
