Use response from calls to insertRecords in tests

Most tests assert the initial record passed into insertRecords. Since we mutate the inserted records to add the uuid this currently works, but in a follow up change we'll update the insertRecords API so it no longer mutates the metadata. This requires changes to most of the cts tests.
