Update tests relying on old log-id
Update tests relying on old log-id

A couple tests relied on checking an old log-id. Those tests in question
will no longer return valid logs (that have been cleaned from our
system) and so the logs need to be updated

- Change the "resend email" test to send an email then verify the resend
  based on the first sent email returned log (rather than a hardcoded
  val)
