The test blindly trusted that there may be _some_ entries left in the rerere database, and used them by updating their timestamps to see if the gc threshold variables are honoured correctly. This won't work if there is no entries in the database when the test begins.
Instead, clear the rerere database, and populate it with a few known entries (which are bogus, but for the purpose of testing "garbage collection", it does not matter---we want to make sure we collect old cruft, even if the files are corrupt rerere database entries), and use them for the expiry test.
