api-testing: Further increase ETag number in transform tests

Change I5521b7652f (commit 682a19e) increased the number by roughly
one order of magnitude, which leaves me nervous that the tests might
start failing again if enough other tests are run in the same wiki to
let the increased revision IDs exist. Let’s bump it further to make that
much less likely (though not impossible).

1219844647 is an arbitrary large number; my intention in choosing a
random-looking number (rather than, say, 1234567890) is that it’s easier
to search for, both in codesearch and in commit messages, if it should
ever pop up in an error message.
