Fix more flaky autofill tests.

Fix more flaky autofill tests.

These were flaky because we changed to returning profiles in reverse chronological order: https://codereview.chromium.org/600873002

The tests assumed normal chronological order. It only failed sometimes because frequently two items would get inserted with the same timestamp, so ordering fell back to GUID. Thus by placing sleep(1) in between AddProfile calls, the flaky failures become consistent failures.
